SHEET PROCESSING DEVICE AND IMAGE FORMING DEVICE

To provide a sheet processing device that can increase the degree of freedom in binding processing of multiple types even if it is small.SOLUTION: A sheet processing device includes loading means for loading a sheet-like medium to form a sheet bundle, first binding means for performing a first binding process for binding a bundle of sheets using a binding member, and second binding means for performing a second binding process for binding a bundle of sheets without using a binding member. The loading means operates so that the end of the sheet bundle and the first binding means are relatively close to each other when the binding process selected for the sheet bundle is the first binding process, and operates so that the end of the sheet bundle and the second binding means are relatively close to each other when the binding process selected for the sheet bundle is the second binding process.SELECTED DRAWING: Figure 3 【課題】小型であっても複数種類の綴じ処理の自由度を高めることができるシート処理装置を提供する。【解決手段】シート状の媒体を積載してシート束を形成する積載手段と、綴じ部材を用いてシート束を綴じる第一綴じ処理を行う第一綴じ手段と、綴じ部材を用いずにシート束を綴じる第二綴じ処理を行う第二綴じ手段と、を備え、積載手段は、シート束に対し選択された綴じ処理が第一綴じ処理のときは、シート束の端部と第一綴じ手段とを相対的に近づけるように動作し、シート束に対し選択された綴じ処理が第二綴じ処理のときは、シート束の端部と第二綴じ手段とを相対的に近づけるように動作する、シート処理装置。【選択図】図３
