Abstract:
1. A sheet processing apparatus comprising: a sheet discharge portion which discharges a sheet; a sheet stacking portion which has an inclined sheet stacking surface on which the sheet discharged by the sheet discharge portion is stacked; first and second gripping members which each grip the sheet at two positions being away from each other in a direction along the inclination of the sheet stacking surface, and are movable in the direction along the inclination of the sheet stacking surface; a sheet processing portion which processes the sheet; and a controlling portion which controls movement of the first and the second gripping members so as to adjust a position of the sheet gripped by the first and the second gripping members corresponding to the sheet processing portion in the direction along the inclination of the sheet stacking surface, wherein, when the sheet is moved in a direction from the second gripping member to the first gripping member, the controlling portion controls so that start timing of the movement of the first gripping member is set relatively earlier than start timing of the movement of the second gripping member.
