Abstract:
1. A sheet processing apparatus comprising: a sheet stacking portion on which sheets are stacked; a folding portion which performs a double folding process to a sheet bundle made of a plurality of sheets which are stacked on the sheet stacking portion; a folded bundle conveying portion which conveys a folded bundle double folded by the folding portion; a folded end portion processing portion which processes a folded end portion of the folded bundle by abutting the folded end portion and moving in a direction orthogonal to a conveying direction; a folded bundle stacking portion on which a folded bundle discharged from the folded bundle conveying portion is stacked; a folded bundle transfer portion disposed on the folded bundle stacking portion, the folded bundle transfer portion moving the folded bundle stacked on the folded bundle stacking portion between a first stacking position where an upstream edge thereof in the conveying direction does not interfere with the folded end portion processing portion during a folded end portion processing, and a second stacking position which is closer to the folded bundle conveying portion than the first stacking position, such that the upstream edge in the conveying direction of the folded bundle stacked on the folded bundle stacking portion is positioned upstream in the conveying direction of a downstream edge in the conveying direction of the folded bundle to be discharged by the folded bundle conveying portion; and a controller which controls operations of the folded bundle conveying portion, the folded end portion processing portion, and the folded bundle transfer portion, wherein the controller:
