Fixing device and image forming apparatus

An image forming device, includes: a transfer unit that transfers a toner image onto a recording medium being conveyed; a main heating unit that is disposed at a downstream side of the transfer unit in a conveyance direction of the recording medium, heats the recording medium in contact with the recording medium, and fixes the toner image to the recording medium; a reversing unit that reverses front and back of the recording medium having the toner image fixed on a first surface of the recording medium by the main heating unit, and sends the recording medium to the transfer unit; a preheating unit that is arranged between the transfer unit and the main heating unit in the conveyance direction of the recording medium and heats the recording medium in a non-contact state, the preheating unit being configured to heat the recording medium so that, when the recording medium that is sent to the transfer unit by the reversing unit and on which the toner image is transferred to a second surface is heated, a temperature of the first surface of the recording medium is higher than a softening point of a toner before the recording medium is heated by the main heating unit; and a non-contact unit that brings a toner image forming region on the first surface of the recording medium on which the toner image is transferred onto the second surface and a member other than the recording medium between the preheating unit and the main heating unit in a non-contact state.

Image forming device conveying sheet in a non-contact state between a preheating unit and a main fixing unit

An image forming apparatus includes: an image forming part that forms an image at an image formation position on one surface of a recording medium; a transport part that transports the recording medium while holding a front end side of the recording medium so that the recording medium passes the image formation position; a transport body that transports the recording medium together with the transport part while supporting the other surface of the recording medium on which an image is to be formed by the image forming part; and a support part that supports the other surface of the recording medium, and the support part starts the support before the other surface of the recording medium is separated from the transport body as a result of transport by the transport part.

Image forming apparatus

A fixing device includes: a holding part that extends in a width direction of a recording medium being transported and that holds the recording medium; a pair of circulating parts that are attached to both ends of the holding part and that circulate to transport the recording medium; and a heating member that heats the recording medium in a non-contact manner and that is located in a space between the pair of circulating parts in the width direction.

An image forming apparatus includes: a transport unit that transports an object along a transport path; a transfer unit that transfers an image onto the object on the transport path; and a fixing unit that has a heat source for increasing a temperature inside the fixing unit, into which the object onto which the image has been transferred is carried along the transport path, and includes a first opening and closing member that opens a carry-in opening when the object is carried into the fixing unit and closes the carry-in opening after the object is carried into the fixing unit.

A transport device includes: a first rotating body including a shaft portion, a cylindrical portion on an outer periphery of the shaft portion, and a recessed portion in an outer surface of the cylindrical portion; a second rotating body capable of moving from the first rotating body while contacting an outer surface of the first rotating body and nipping a recording medium; a transport unit that includes a holding portion that holds the recording medium, and that transports the recording medium by moving the holding portion in a rotation direction of the first rotating body while the holding portion is disposed in the recessed portion; and a moving mechanism including a cam portion on a side of the cylindrical portion and a contact portion connected to the second rotating body and that comes into contact with the cam portion to separate the second rotating body from the first rotating body.

Transport device, fixing device, and image forming apparatus

A recording medium transport device includes: a circulating member that forms a part of a transport path for transporting a recording medium; a holding member that is fixed to the circulating member and thereby circulates and holds a front end portion of the recording medium; plural transport cylinders around which the circulating member is suspended and having a recessed part in which the holding member is stored; and a selection part that selects any one of the plural transport cylinders. A mode for stopping the selected one of the plural transport cylinders so that the recessed part of the selected one of the plural transport cylinders is located at a maintenance position is prepared.

Recording medium transport device and image forming apparatus

A transportation device includes a first transporter, a second transporter movable between a contact position and a separate position toward and away from the first transporter to hold a to-be-transported object between the second transporter and the first transporter in the contact position, and a transportation unit that transports the to-be-transported object to a nip area where the first transporter and the second transporter hold the to-be-transported object therebetween while the second transporter is located in the separate position. The second transporter moves from the separate position to the contact position to hold the to-be-transported object transported to the nip area by the transportation unit between the second transporter and the first transporter to transport the to-be-transported object.

Transportation device, fixing device, and image forming apparatus

A transport device includes: a first transport body; a second transport body that is movable between a contact position and a separate position with respect to the first transport body and that nips a transported material with the first transport body at the contact position; and a transport section that includes a holder to hold a leading end portion of the transported material and that transports the transported material toward a nip region where the first transport body and the second transport body nip the transported material in a state in which the second transport body is located at the separate position. After holding of the leading end portion by the holder for the transported material transported by the transport section has been released, the second transport body nips the transported material with the first transport body and transports the transported material.

A heating device includes: a heating unit configured to heat a transported material being transported in a transport direction in a non-contact manner with respect to the transported material; and a facing portion that is disposed on a side opposite to the heating unit with respect to the transported material and faces the heating unit in a facing direction intersecting the transport direction, wherein a length of the heating unit in the transport direction is longer than a length of the facing portion in the transport direction, or a length of the heating unit in an intersecting direction intersecting the transport direction and the facing direction is longer than a length of the facing portion in the intersecting direction.

Heating device and image forming apparatus
