An image forming apparatus includes: a transfer unit that faces an image holding unit and is configured to come into contact with and separate from the image holding unit with a continuous form paper continuous in a transport direction interposed between the transfer unit and the image holding unit and to transfer an image held by the image holding unit onto the continuous form paper; a displacement unit that displaces the continuous form paper to a position closer to the image holding unit when the transfer unit separates from the image holding unit; and a contact portion that contacts the continuous form paper from a downstream side in a displacement direction before the continuous form paper displaced by the displacement unit contacts the image holding unit.

Image forming apparatus

An image forming apparatus includes: a transfer member that transfers a toner image to a continuous sheet, the transfer member having a lower hardness than a member opposed thereto with the continuous sheet therebetween when the continuous sheet is transported; and a moving unit that moves the transfer member in a direction intersecting the direction in which the continuous sheet is transported.

Provided is an image forming apparatus including an image forming unit that forms an image on a recording medium, and an applying unit that causes powder included in a liquid mixture to be interposed between the recording medium and the image forming unit by applying the liquid mixture to the recording medium, or to the image forming unit which comes into contact with the recording medium, wherein the recording medium includes an image forming layer, an adhesive layer, and a base layer, and the liquid mixture includes the powder reducing adhesion of the adhesive layer and volatile liquid.

A fixing device includes a heating member that has a heat source, comes into contact with a surface of a continuous medium having an image transferred thereto and heats the surface; a pressure member that is provided so as to oppose the heating member with the medium therebetween and applies pressure to the medium; and a tensioning member that is provided on a downstream side of a fixing area, where the heating member and the pressure member oppose each other, in a medium-transport direction, applies tension to the medium by pressing the medium toward the pressure member, and wraps the medium around the pressure member.

Fixing device and image forming apparatus

A fixing device includes a rotatable fixing member provided in a fixing area where an unfixed image on surface of a medium is fixed, the fixing member including at least a thermoplastic surface layer that softens at a temperature below a fixing temperature at which the image is fixed; and a cleaning member provided on a downstream side with respect to the fixing area in a direction of rotation of the fixing member and that cleans the fixing member while coming into contact with a hardened portion of the fixing member in a cleaning area, the cleaning area being at a temperature below the temperature at which the thermoplastic surface layer of the fixing member softens.

A cooling device cools a continuous resin film, which is transported and onto which a toner image is transferred, after the toner image is heated so that the toner image is fixed to the resin film. The resin film to which the toner image is fixed is cooled in such a manner that an image surface side of the resin film is convexly curved.

Cooling device, image forming apparatus, and cooling method

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.

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.

Image forming apparatus, image forming method, and computer readable medium having image density adjustment control

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.

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 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.
