PROBLEM TO BE SOLVED: To provide a sheet processing device capable of inhibiting poor conveyance and formation of a scratch on a sheet, an image forming apparatus comprising the sheet processing device, and an image forming system.SOLUTION: After binding processing is performed for a paper bundle Ps, a binding tool 210 is shifted from a binding position to a receding position that is a home position. The binding tool 210 is shifted to the receding position so that paper stuck on a lower serrated form can come off. When the binding tool 210 is shifted to the receding position, the paper bundle Ps is conveyed by starting to drive a paper ejection roller. 【課題】搬送不良やシートの傷つきを抑制することができるシート処理装置、このシート処理装置を備えた画像形成装置および画像形成システムを提供する。【解決手段】用紙束Ｐｓに対して綴じ処理を行った後、綴じ位置から、ホームポジションである退避位置へ綴じ具２１０を移動させる。綴じ具２１０を退避位置へ移動させることにより、下歯型に張り付いていた用紙が剥がれる。そして、綴じ具２１０が、退避位置へ移動したら、排紙ローラの駆動を開始して、用紙束Ｐｓを搬送する。【選択図】図２１
