ABSTRACT:
A sheet processing apparatus including: a conveying unit, which conveys a sheet; a stacking unit on which the conveyed sheet is stacked; a processing unit, which processes the stacked sheet; a buffering unit, which allows the sheet conveyed to the stacking unit by the conveying unit to pass, and buffers a predetermined number of sheets to be passed during an operation of the processing unit; a transferring unit, which receives the buffer sheets and transfers the predetermined number of buffer sheets from the buffering unit to the stacking unit; and a controlling unit, which controls a sheet conveying speed to make a speed when the transferring unit transfers the buffer sheet lower than a speed when the transferring unit receives the buffer sheets to prevent the sheet conveyed by the conveying unit from interfering the transferring unit during an operation of transferring the sheet.
