An image forming apparatus includes an image forming part to form an image on a medium and a photo-finishing part to thermally transfer a coating film covering the image onto the medium.

A photocuring printing system. A developing drum is rotatable and is light-transmissive; the developing drum and a carrier are oppositely arranged and movable with respect to each other; the developing drum has a developing surface on which an electrostatic latent image is formed by the developing engine; a feeder and the developing surface are oppositely arranged; during a rotation of the developing drum, a photocurable material provided by the feeder is selectively attracted by the electrostatic latent image to form a material layer on the developing surface; the material layer is applied, by the developing drum, on a forming surface of the carrier or a cured model on the carrier; and a curing light beam emitted by a curing light source passes through a material-laying side of the developing drum to irradiate the material layer between the developing drum and the carrier to form a cured layer.

An image forming apparatus includes a sheet separation device, a first sheet feeder, a second sheet feeder, an image forming device, and circuitry. The sheet separation device is configured to separate a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The first sheet feeder is configured to feed the two-ply sheet. The second sheet feeder is configured to feed an inner sheet to be inserted between the two sheets. The image forming device is configured to form an image on a surface of the inner sheet. The circuitry is configured to cause the first sheet feeder to feed the two-ply sheet, perform a sheet separating operation on the two-ply sheet and cause the second sheet feeder to start feeding the inner sheet before completion of the sheet separating operation on the two-ply sheet.

The image reading unit (2) reads an image from a document. The image forming unit (3) is located below the image reading unit (2) and forms an image on a sheet. The operation unit (5) is rotatably supported at a position forward of the image reading unit (2) and receives user's operation. The post-process unit (7) is provided between the image reading unit (2) and the image forming unit (3), and has, at a position interfering with the rotation range of the operation unit (5), a retracted portion (772) retracted rearward in the post-process unit (7). The post-process unit (7) performs a post-process on a sheet on which an image has been formed by the image forming unit (3).

An image forming apparatus includes an image carrier; a transfer unit that transfers an image carried by the image carrier to a continuous medium; a fixing device including a first fixing member that contacts the continuous medium and heats the image transferred to the continuous medium and a second fixing member that is disposed so as to face the first fixing member with the continuous medium therebetween and presses the image, the fixing device fixing the image transferred to the continuous medium, the fixing device being configured so that the first fixing member and the second fixing member are capable of contacting or separating from each other; and a separation member that contacts the continuous medium and separates the continuous medium from the first fixing member when the first fixing member and the second fixing member separate from each other.

A post-processing apparatus includes a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing portion that houses the removed side edge part and is able to be pulled out from an apparatus body; a guide plate that is inclined in a direction intersecting with a moving direction of the side edge part and guides the removed side edge part along the moving direction to the housing portion; and a second guide plate that is arranged between the housing portion and the guide plate, and is transformable into a first form having substantially mountain-shaped inclined surfaces in which both end portions of the second guide plate along the moving direction are lower than a center portion thereof, and a second form having substantially valley-shaped inclined surfaces in which both the end portions are higher than the center portion.

A post-processing apparatus includes a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing portion that houses the side edge part of the sheet removed by the side edge part removing portion; and a side edge part action portion that acts on the removed side edge part and moves at least a portion of the side edge part.

A post-processing apparatus includes a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing section that houses the side edge part removed by the side edge part removing portion and that is able to be pulled out from an apparatus body; and a guide plate that is inclined in a direction intersecting with a moving direction of the side edge part and guides the side edge part removed by the side edge part removing portion along the moving direction of the side edge part to the side edge part housing section.

A cutting device is configured to cut, in an arc shape, an end of a sheet conveyed in a conveyance direction. The cutting device includes an arc-shaped cutting blade; a switching mechanism; and a contact-and-separation mechanism. The switching mechanism is configured to switch a posture of the cutting blade in accordance with a position of the sheet facing the cutting blade. The contact-and-separation mechanism is configured to bring the cutting blade into contact with the sheet in a contact direction orthogonal to a surface of the sheet and away from the sheet in a separation direction opposite the contact direction, to cut the end of the sheet in the arc shape.

A sheet conveyance guide includes a sheet material. The sheet material has a surface to face a sheet when the sheet conveyance guide guides the sheet travelling in a conveyance direction. The sheet material has irregularities over a whole area of the surface.
