Sheet processing apparatus and image forming apparatus

摘要

The present invention provides a sheet processing apparatus (C) and an image forming apparatus (B) in which even if the apparatus includes a gripping apparatus gripping one side of a sheet bundle to be stapled, the sheet bundle can be stapled in a portion thereof in which the gripping apparatus is located. A gripper unit (40) is moved in a direction crossing one side of sheets and placed in a discharge position in which the gripper unit (40) discharges the gripped sheets and in a coupling position where the gripper unit (40) is coupled to a staple unit (41). The gripper unit (40) is thus moved in the same direction as that in which the staple unit (41) coupled to the gripper unit (40) at the coupling position moves. Thus, the staple unit (41) can be moved to a stapling position without the need to ensure a retract space.
