Claim Text:
1. A sheet processing apparatus comprising: a stacking unit on which a sheet is stacked; an ejecting unit that ejects a sheet, on which a toner image has been heated and fixed, onto the stacking unit; a processing unit that processes a sheet ejected by the ejecting unit; and a control unit configured to control the ejecting unit, wherein the control unit controls the ejecting unit to bring a sheet into a state in which the sheet overlaps with the stacking unit over the stacking unit, and in the state in which the sheet overlaps with the stacking unit over the stacking unit, the control unit causes the ejecting unit to execute a reciprocating operation of the sheet and then to eject the sheet onto the stacking unit, and wherein the control unit causes the ejecting unit to stop the sheet for a predetermined time in the reciprocating operation of the sheet while the sheet is in the state in which the sheet overlaps with the stacking unit over the stacking unit, the predetermined time being set so that the predetermined time is sufficient to prevent the sheet from adhering to a preceding sheet stacked on the stacking unit.
