とする請求項１記載のシート後処理装置。[Claims for Utility Model Registration] (1) A stapler that pierces a staple of a predetermined shape through a bundle of sheets discharged from an image forming apparatus and is stacked, and then bends the end of the needle to staple the bundle of sheets. In the sheet post-processing device, the stapler is provided with a pressing plate that presses the staple against the sheet bundle, and is provided on the opposite side of the pressing plate and abuts against the end of the staple, bending the end, and It has an electrically conductive bending member that moves in the pressing direction of the press plate in response to needle tip pressure, and an electrical contact that opens and closes by the movement of the bending member, and performs the binding process from opening and closing of the electrical contact. A sheet post-processing device that is capable of detecting the quality of the sheet. (2) The sheet post-processing device according to claim 1, wherein the pressing plate has conductivity and detects opening/closing of the electrical contact via the pressing plate.
