An image forming apparatus includes a transport unit that transports a recording medium; a forming unit that forms a toner image on the recording medium, the toner image including a resin and a flat metallic pigment; a fixing unit that fixes the toner image to the recording medium by heating and pressing the toner image; and a cooling unit that cools the toner image fixed by the fixing unit, the cooling unit being disposed at a position at which the cooling is started when a temperature of the toner image is higher than or equal to a glass transition temperature.

Image forming apparatus and image forming method

An image forming apparatus includes a transport module that is capable of being pulled out from an apparatus body of the image forming apparatus and in which a transport path along which a recording material, to which a toner image has been transferred, is to be transported is formed and a fixing unit that is provided in the transport module and that includes a fixing member, which fixes the toner image onto the recording material, and a pressure member, which forms a pressing part to which the recording material is to be transported between the fixing member and the pressure member. When the recording material whose length in a transport direction is longer than that of the transport module is present in the transport path, the transport module is pulled out from the apparatus body while the recording material is being nipped by the fixing member and the pressure member.

Image forming apparatus and image forming system

A fixing device includes a fixing member that fixes a toner image to a recording medium, a pressure member that forms, together with the fixing member, a pressure portion through which the recording medium carrying the toner image yet to be fixed passes, and a heating member including a heating layer that generates heat when energized and an insulating layer that encloses the heating layer so as to electrically insulate the heating layer. The heating member has a curved shape along an inner peripheral surface of the fixing member, in a state in which no external force is applied, and is in contact with the inner peripheral surface of the fixing member.

Fixing device, heating device, image forming apparatus, and method of manufacturing heating device

A fixing device includes a heating unit that heats an unfixed image on a recording medium, which is deformed by heating, and hence fixes the unfixed image; and a transport member that closely contacts a no-image surface of the recording medium and transports the recording medium while causing a close contact force to act on the recording medium against a deformation force, which is generated at the recording medium by the heating of the heating unit. The close contact force of the recording medium with respect to the transport member is larger than the deformation force generated at the recording medium.

Fixing device and image forming apparatus

An image forming apparatus includes an image forming unit and a controller. The image forming unit forms an image on a continuous recording medium by transferring to the continuous recording medium a toner image obtained by developing a latent image formed on a photoreceptor. The controller controls the image forming unit such that an image based on image information is formed in a specific image area on the continuous recording medium, and at the same time, a specific image pattern is formed in a specific side area outside the image area on the continuous recording medium.

A fixing device includes a fixing rotary body that heats and pressurizes, together with a recording medium, toner having particle diameter of 4.5 [&#x3bc;m] or less and a softening point of 100 [&#xb0; C.] or higher and 125 [&#xb0; C.] or lower to fix the toner on the recording medium, a heating unit that heats the fixing rotary body, and a pressurizing unit that sandwiches and pressurizes the toner and the recording medium in a contact part formed by the fixing rotary body, wherein the maximum pressure in the contact part is equal to or more than 2.9&#xd7;10[Pa], the width of the contact part in a movement direction of the recording medium is equal to or more than 10 [mm], and the heating time of the toner in the contact part is equal to or more than 20 [msec].

An image forming apparatus includes a toner image holding member, a transfer unit, and a supply unit. The toner image holding member holds a toner image. The transfer unit transfers the toner image held by the toner image holding member to a recording medium. The supply unit supplies powder such that the powder is interposed between an end portion of the recording medium and the toner image holding member and/or the transfer unit if the recording medium includes an intermediate adhesive layer.

Image forming apparatus

A fixing device includes a fixing section that includes rotatable members arranged to form a nip area through which a strip-shaped medium passes, and heaters that heat the rotatable members; and a control section. The fixing section applies heat and pressure to a toner image that is formed on the medium and passes through the nip area via the rotatable members heated by the heaters to fix the toner image onto the medium. The control section performs such control that the rotation of the rotatable members is stopped when the temperature of contact portions of the rotatable members that are in contact with the medium is lower than or equal to a first temperature that is lower than a temperature at which a portion of the medium softens.

An image forming apparatus includes an image forming unit that forms an image on a recording material; an endless belt member; a pressure member that applies pressure to the belt member; a pressing member that presses the belt member from an inner side of the belt member towards the pressure member; and an adjusting section that adjusts a position of an end portion of a nip part at a downstream side in a movement direction of the recording material and a position of a curved portion of the belt member by moving or deforming the pressing member, the nip part being formed by the belt member and the pressure member, the curved portion of the belt member being formed by an end portion of the pressing member at a downstream side in the movement direction of the recording material.

Image forming apparatus and fixing device

An image-forming apparatus includes an image unit that forms an image using at least one of a white toner and a color toner having a lower storage modulus than the white toner and a fixing unit that fixes the image to a medium with heat. A time P calculated by subtracting a fixing time for which an image of the color toner alone is fixed to normal paper used as the medium from a fixing time for which an overlaid image of the white toner and the color toner is fixed to color paper used as the medium is more than 0 ms and less than 30 ms.

Image-forming apparatus

A fixing device includes: an endless belt member; a secured member disposed to contact the belt member; a support roller that rotatably supports the belt member; a heating unit that heats the belt member; and a rotary pressurizing roller that includes an elastic surface layer that is elastically deformed when the belt member is pressed against the secured member to form a fixing part. The secured member includes a recessed part provided on a surface of the secured member that faces the pressurizing roller and configured to curve the belt member into a recessed shape, projecting parts provided upstream and downstream of the recessed part, respectively, and configured to curve the belt member into a projected shape, and a region provided between at least one of the projecting parts and the recessed part and having a small curvature compared to the corresponding projecting part.

A fixing device includes a heat assembly including an endless belt, a heat source, an attachment member having an attachment surface and first and second side surfaces, and a slide sheet having first and second end portions that are respectively fixed to a first fixing portion at the first side surface and a second fixing portion at the second side surface, the slide sheet having a larger length from the first end portion to the second end portion than a length of a path of the attachment member extending from the first fixing portion to the second fixing portion through the first side surface, the attachment surface, and the second side surface; and a pressure roller that presses the outer surface of the endless belt to the attachment surface.

A recording medium peeling device includes: a circularly moving section that has a moving surface circulating along a circulation course; and a pressing section that presses a recording medium passing through a pressing position in the circulation course, against the moving surface at the pressing position. The recording medium peeling device further includes: a peeling member that is disposed downstream from the pressing position in the circularly moving, is apart from the moving surface, is provided along the moving surface, extends in a direction crossing a direction of the circularly moving, and peels the recording medium after passing through the pressing position from the moving surface; and a protruding member that is disposed downstream from the peeling member in a direction in which the recording medium after being peeled by the peeling member proceeds, protrudes from the peeling member side to the recording medium side, and slopes downstream.
