Abstract
The present invention is to provide a sheet bundle binding device having both a staple binding unit and a staple-free binding unit, capable of performing binding in two stages of proper binding and temporary binding so as to obtain a desired binding force and to easily remove some sheets from a bound sheet bundle. A binding control section determines, based on user's settings, whether or not to perform first binding in which a first sheet bundle Sb1 is subjected to the proper binding using the staple binding unit or staple-free binding unit and determines whether or not to perform second binding in which a second sheet bundle obtained by accumulating additional sheets on the first sheet bundle is subjected to the temporary binding using the staple-free binding unit so as to control binding forces with which the first and second sheet bundles are bound.
