SHEET PROCESSING DEVICE AND IMAGE FORMATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a sheet processing device and an image formation device capable of performing binding processing without increasing size and reducing processing efficiency even when binding means is used whose height of a reception part is different.SOLUTION: Binding processing is performed by a stapler 110 with a staple to a sheet bundle ejected to an intermediate processing tray 107 in a state of receiving the sheet bundle in a reception part, and the binding processing is performed by a non-staple binding unit 102 with no staple to the sheet bundle ejected to the intermediate processing tray 107 in a state of receiving the sheet bundle in a reception part whose space in a thickness direction is narrower than that of the reception part of the stapler 110. The non-staple binding unit 102 is placed at a position that is displaced in a width direction orthogonal to a sheet ejection direction from a region on the intermediate processing tray 107 through which the sheet ejected by sheet ejection means passes when the binding processing is performed by the stapler 110.
