    摘要： An image forming apparatus includes a sheet separation device, a first sheet feeder, a second sheet feeder, an image forming device, a heat source, and a circuitry. The sheet separation device is configured to separate a two-ply sheet in which two sheets are overlapped and bonded together at one end as 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 the inner sheet fed from the second sheet feeder. The heat source is disposed upstream from the sheet separation device in the sheet conveyance direction. The circuitry is configured to cause the two-ply sheet fed from the first sheet feeder, to detour the heat source to the sheet separation device.

    摘要： A sheet processing device includes: a conveying module that conveys a folded sheet; and a pressing module that presses a folded part of the folded sheet by rotating about a direction orthogonal to a sheet conveying direction of the conveying module as a rotation axis. The pressing module includes a projecting part arranged in a certain range in a direction of the rotation axis along a circumferential surface about the rotation axis. The projecting part is formed to be symmetric with respect to a middle part of the rotation axis in the direction of the rotation axis, and the projecting part arranged on one side from the middle part along the direction of the rotation axis are formed such that a position of the projecting part in a rotational direction of the circumferential surface varies along the direction of the rotation axis.

    摘要： A sheet laminator includes a sheet separation device, a sheet insertion device, and circuitry. The sheet separation device is configured to perform a sheet separating operation 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, and a sheet inserting operation to insert an inner sheet between the two sheets. The sheet lamination device is configured to perform a sheet laminating operation on the two-ply sheet after the sheet separating operation and the sheet inserting operation. The circuitry is configured to cause the sheet lamination device to perform the sheet laminating operation on the two-ply sheet while causing the sheet separation device to perform the sheet separating operation on another two-ply sheet subsequent to the two-ply sheet or the sheet separating operation and the sheet inserting operation on said another two-ply sheet.
