At the point in time when it is determined that the number of sheets constituting one sheet bundle exceeds the maximum number of sheets that can be crimp-bound, a sheet bundle that has already been shifted to a crimp-binding position is discharged to a crimp-binding discharge position without being subjected to crimp-binding. Thereafter, succeeding sheets are shifted as a bundle to the crimp-binding position and discharged to the crimp-binding discharge position without being subjected to crimp-binding.

Sheet processing apparatus and image forming system having the same

To enable highly accurate fold processing by properly moving a sheet that has been subjected to fold processing. In a sheet processing apparatus that that performs fold processing in such a manner as to apply first fold processing to a sheet and then apply second fold processing at a position different from a fold line formed in the first fold processing so as to make one end of the sheet folded in the first fold processing lie inside the folded sheet, the first fold processing is applied to a sheet conveyed to an intermediate tray by a fold roller pair and, when a regulating stopper is moved to move the folded sheet that has been subjected to the first fold processing to a predetermined position of the intermediate tray, the folded sheet is gripped by a grip unit.
