摘要： A sheet processing device is configured to separate a non-bonding portion of 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 sheet processing device includes a first sheet feeder configured to feed the two-ply sheet, a second sheet feeder configured to feed an inner sheet to be inserted between the two sheets of the two-ply sheet in a state in which the non-bonding portion of the two-ply sheet is separated, and circuitry configured to cause the first sheet feeder to feed the two-ply sheet, perform a sheet separating operation on the two-ply sheet to separate the non-bonding portion of 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.

摘要： A sheet processing device sandwiches a sheet-shaped medium in a two-ply sheet in which two sheets are overlaid and partially bonded. The sheet processing device includes a separator, a conveyor, and a switching member. The separator separates the two sheets of the two-ply sheet. The conveyor is disposed downstream from the separator in a sheet conveyance direction and conveys the two-ply sheet. The switching member is disposed downstream from the conveyor in the sheet conveyance direction. The switching member switches a conveyance path of the two-ply sheet to convey the two-ply sheet to a fixing path on which fixing processing is performed on the two-ply sheet or a non-fixing path on which no fixing processing is performed on the two-ply sheet.

摘要： A 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 one end as a bonding portion of the two-ply sheet. The sheet separation device includes a conveyance roller pair and circuitry. The conveyance roller pair is configured to convey the two-ply sheet while nipping the two-ply sheet, when separating the non-bonding portion of the two-ply sheet. The circuitry is configured to control sheet conveyance. The circuitry is configured to stop the conveyance roller pair, cause a leading end of the two-ply sheet conveyed toward the conveyance roller pair to contact a nip region of the conveyance roller pair while the conveyance roller pair is stopped, and start the conveyance roller pair to rotate to nip the two-ply sheet.

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.

摘要： An image forming system includes an image forming apparatus, a sheet processing device, and control circuitry. The image forming apparatus forms an image on a sheet. The sheet processing device performs post-processing on the sheet. The sheet processing device includes a first conveyance path through which the sheet is conveyed and subjected to the post-processing and a second conveyance path through which the sheet is conveyed without the post-processing. In response to an instruction of print jobs including both a print job of one or N copies subjected to the post-processing and a print job not subjected to the post-processing, the circuitry executes the job not subjected to the post-processing during execution of an M-th copy of the job subjected to the post-processing and causes the sheet to be conveyed through the second conveyance path, where N is two or greater and M satisfies 1≤M
