A sheet processing apparatus includes a binding portion binding a plurality of sheets stacked on a sheet stacking portion as a bundle by deforming the sheets without a staple. The sheet processing apparatus further includes a moving member moving the sheet bundle bound at a binding position by the binding portion from the binding position and a restricting member restricting the move of the sheet bundle such that a distance between the sheet bundle and the moving member is kept to be less than a predetermined distance in moving the sheet bundle by the moving member.

A sheet aligning device includes a support member, a regulation member, a regulation member moving mechanism, and an alignment member. The support member supports leading ends of sheets. The regulation member is connected to the support member and is provided to face an inclined tray in such a way as to define a sheet entry space in which the leading ends of the sheets enter. The regulation member moving mechanism is configured to, each time a sheet is conveyed onto the inclined tray, move the regulation member in a separating direction to widen the sheet entry space, and then in an approaching direction to narrow the sheet entry space. The alignment member aligns the sheets by abutting on rear ends of the sheets.

A sheet processing apparatus includes a conveying portion, a stack portion on which sheets are stacked, a first binding portion moving in a crossing direction crossing a conveying direction, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a first rack moving in the crossing direction with the first regulating portion, a first pinion forming a rack-pinion mechanism with the first rack, a second regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a second rack moving in the crossing direction with the second regulating portion, a second pinion forming another rack-pinion mechanism with the second rack, a third regulating portion regulating a position of a sheet bundle stacked on the stack portion, and a second binding portion which binds a corner portion of a sheet bundle without a staple.

A sheet conveyance apparatus includes a rotary member pair, a movement portion, a detection portion, an abutment member, an oblique conveyance portion, and a controller configured to, on a basis of a detection result of the detection portion, move the rotary member pair in a width direction by the movement portion such that a position, in the width direction, of the downstream end of the sheet is a set position in a state in which the rotary member pair is nipping the sheet and before the sheet reaches the oblique conveyance portion. The controller is configured to execute, after the sheet has reached the oblique conveyance portion, a correction mode of correcting the set position on a basis of the position of the downstream end, abutting the abutment surface, detected by the detection portion.
