ABSTRACT:
The sheet processing apparatus has a stapling unit which staples a sheet bundle by clinching the sheet bundle, of which sheets sequentially enters an opening between a first stapling part and a second stapling part and are then stacked, and a controller which controls the stapling parts. When executing a stapling process of the sheet bundle, an opening distance between the stapling parts before starting a stapling operation becomes narrower than an opening distance set till the last sheet of the sheet bundle enters (approaches) between the stapling parts. This contrivance enables reduction of the time required for the stapling process of the sheet bundle and an improvement of the productivity irrespective of the number of points for the stapling process without scaling up the apparatus, causing any complicated configuration of the apparatus and increasing the costs.
