Abstract:
1. A sheet processing apparatus that stacks sheets received from two image forming apparatuses in a processing portion and processes a sheet on the processing portion, comprising: a first discharging portion that comprises a pair of discharge rollers and discharges a sheet received from one of the two image forming apparatuses to the processing off; a second discharging portion that is disposed so as to be opposite to the first discharging portion with respect to the processing portion and discharges a sheet received from the other image forming apparatus of the two image forming apparatuses to the processing portion; and a controller that controls the first discharging portion and the second discharging portion, wherein the pair of discharge rollers of the first discharging portion is disposed so that a nipping line extending from a nipping point of the discharge rollers and being perpendicular to a line passing through both rotary centers of the discharge rollers inclines in a sheet discharge direction downward so as to extend below a horizontal line extending horizontally in the sheet discharge direction from the nipping point, and when the sheets are continuously discharged by the first discharging portion and the second discharging portion to the processing portion, the controller controls the first discharging portion and the second discharging portion such that a leading edge of the sheet discharged by the second discharging portion abuts on a sheet surface of the sheet being discharged by the first discharging portion to drop the sheet down on the processing portion which is disposed below the first discharging portion and the second discharging portion.
