摘要： A sheet processing apparatus includes a sheet conveyance passage, a sheet circulation passage, a first conveyor, a second conveyor, a third conveyor, and circuitry. In the sheet circulation passage, a sheet is circulated to be overlaid with a following sheet in the sheet conveyance passage. The circuitry circulates the sheet in the sheet circulation passage to overlay the sheet with the following sheet conveyed after the sheet in the first sheet conveyance passage, at an upstream position of the first sheet conveyance passage, and adjusts a sheet conveyance speed of the third conveyor to circulate the sheet, based on a reduction amount that is obtained when a preceding amount of a leading end of the following sheet with respect to a leading end of the sheet is reduced while the following sheet is temporarily stopped due to a temporary stop of the first conveyor.

摘要： A post-processing device (200) includes a circulation conveyance path, a zeroth conveyer (R0), and a controller (50). The circulation conveyance path includes a first conveyance path (W1), a second conveyance path (W2), a third conveyance path (W3), a first conveyer (R1), a second conveyer (R2), and a third conveyer (R3). The first and second conveyers convey a preceding sheet (P1) along the first and second conveyance paths. The third conveyer conveys it from the third conveyance path to the first conveyance path. The zeroth conveyer conveys a following sheet (P2) toward the first conveyer. The controller controls the third conveyer to stop the preceding sheet, subsequently controls the zeroth conveyer and the third conveyer to overlay the preceding sheet with the following sheet to form a sheet bundle (Q) having a shift amount (G) between a leading edges of the preceding sheet and the following sheet and strike the leading edges of the preceding sheet and the following sheet against the first conveyer.
