<p>PROBLEM TO BE SOLVED: To reduce distortion of sheets or deviation of a bending position from a creased position caused by a thickness of the sheets which easily occurs when performing a binding process and a creasing process to a sheet bundle.SOLUTION: A CPU 205 of a main controller 201 of an image forming device body 101, when making a creasing device 151 to perform a creasing process to sheets constituting a sheet bundle and causing a binding process for binding the sheet bundle (Yes in a S1301 and a S1302), executes control so that a creasing position is shifted and the creasing process is performed for each sheet constituting the sheet bundle, according to a folding direction of a sheet designated in the creasing process and a binding position in the binding process (S1304-S1311).</p> |
