Abstract
A sheet processing apparatus capable of improving sheet processing performance and productivity is provided. While sheets are conveyed in a piled state toward a rear-end stopper, displacement is produced between the sheets by a pair of discharge rollers. Even if adhesion occurs between the sheets during conveyance thereof, the adhesion between the sheets can be removed before the sheets come into contact with the rear-end stopper.

A sheet processing apparatus comprising:
- a piling portion at which a plurality of sheets are piled;
- a conveying portion capable of conveying the plurality of sheets piled by the piling portion;
- a stacking tray on which sheets conveyed by the conveying portion are stacked;
- and
- a regulation member against which a sheet is abutted to regulate the sheet conveyed to the stacking tray,
- a control portion which controls displacement of the piled sheets to be conveyed toward the regulation member so that the piled sheets are displaced in a sheet conveying direction with respect to each other before the piled sheets are abutted against the regulation member.
