PROBLEM TO BE SOLVED: To provide a post-processing device which can discard the side edge removed from a sheet during execution of the post-processing operation, and provide an image formation system.SOLUTION: A post-processing device includes: side edge removal means which removes the side edge of a sheet; a side edge storage part which can store the side edge of the sheet removed by the side edge removal means and be drawn from the device body; a guide plate which is inclined in the direction intersecting the movement direction of the side edge, and guides the side edge removed by the side edge removal means to the side edge storage part while guiding it along the movement direction of the side edge; and a second guide plate which is arranged between the side edge storage part and the guide plate, and can be deformed into the first form having the mountain-shaped inclined surface whose both ends along the movement direction of the side edge are lower than the center part in conjunction with the drawing operation of the side edge storage part, and into the second form having the valley-shaped inclined surface whose both ends are higher than the center part.SELECTED DRAWING: Figure 9 【課題】用紙から除去された側縁の廃棄を後処理動作の実行中に行うことができる後処理装置及び画像形成システムを提供する。【解決手段】用紙の側縁を除去する側縁除去手段と、側縁除去手段で除去される用紙の側縁を収容し装置本体から引き出し可能な側縁収容部と、側縁の移動方向と交差する方向に傾斜し側縁除去手段で除去された側縁を側縁の移動方向に沿って誘導しながら側縁収容部に導く誘導板と、側縁収容部と誘導板との間に配置され、側縁収容部の引き出し動作に連動して側縁の移動方向に沿う両端部が中央部に比べて低くなっている山型の傾斜面を有する第１の形態と両端部が中央部に比べて高くなる谷型の傾斜面を有する第２の形態とに変形可能な第２の誘導板と、を備えた。【選択図】図９
