Abstract

A sheet processing apparatus comprises a pressurizing unit including a first pressurizing member and a second pressurizing member; and a moving unit moving the pressurizing unit and including a driving motor, wherein the position where a sheet bundle is pressurized by the first pressurizing member and the position where the sheet bundle is pressurized by the second pressurizing member are shifted in the direction of the fold line of the sheet bundle, and a driving condition of the driving motor is changed between a first orientation in which the pressurizing unit moves in the positional relation that the first pressurizing member precedes the second pressurizing member and a second orientation in which the pressurizing member moves in the positional relation that the second pressurizing member precedes the first pressurizing member.
