POST-PROCESSING DEVICE

PROBLEM TO BE SOLVED: To further reduce a possibility that exhaust defect may occur, in comparison with a case where a claw part for retaining rear ends of the recording media is positioned at a higher level, even in a case where recording media such as print sheets stored in a storage part such as a compile tray for executing post-processing are loaded in small number.SOLUTION: A stopper 28 retains rear ends of recording media such as print sheets stored in a compile tray and pushes out the media toward an exhaust port. The stopper 28 has a claw part 32 as a first retaining part for retaining rear ends of recording media loaded in large number and a step part 36 as a second retaining part for retaining rear ends of recording media which are loaded in small number.SELECTED DRAWING: Figure 6 【課題】後処理を実行するためのコンパイルトレイ等の格納部に格納された印刷用紙等の記録媒体の積載枚数が少ない場合でも、記録媒体の後端を掛止めるための爪部を高い位置とした場合に比較して、排出不良が発生する可能性を低くする。【解決手段】ストッパ２８は、コンパイルトレイに格納された印刷用紙等の記録媒体の後端を掛止して排出口に向けて押し出す。ストッパ２８には、積載枚数が多い記録媒体の後端を掛止する第１の掛止部としての爪部３２と、積載枚数が少ない記録媒体の後端を掛止する第２の掛止部としての段差部３６と、を有する。【選択図】図６
