To provide a post-processing device that eliminates the need for sensor installation for positioning a driven member which moves reciprocally and the can reduce costs.SOLUTION: The present invention relates to a post-processing device which performs post-processing on a sheet conveyed from an image formation device, and the post-processing device comprises: a driven member (stapler 50) which is moved reciprocally in predetermined directions; drive means 56 for moving the driven member; and a stopper member 53 which is arranged at both ends of the driven member in moving directions D1 to define a movement range, wherein the driven member is moved until it abuts on a stopper member 53, and when one of drive limit positions where the driven member stops is considered as a reference position, the driven member starts at the reference position when moved to a predetermined position.SELECTED DRAWING: Figure 3 【課題】往復移動する被駆動部材の位置決めをするためのセンサ設置が不要で、コスト削減を実現可能な後処理装置を提供する。【解決手段】画像形成装置から搬送された用紙に対して後処理を施す後処理装置であって、所定の方向へ往復移動する被駆動部材（ステープラ５０）と、被駆動部材を移動させるための駆動手段５６と、被駆動部材の移動方向Ｄ１の両端に配設され、移動範囲を規定するストッパ部材５３と、を備え、被駆動部材をストッパ部材５３に当接するまで移動させ、被駆動部材が停止した駆動限界位置の一方を基準位置とし、所定の位置に被駆動部材を移動させるとき、基準位置を起点とする。【選択図】図３
