ABSTRACT:
The object of the present invention is to provide a sheet processing apparatus for passing sheets between an upper jaw and a lower jaw of a binder that is fixed on a intermediate stacking portion and stapling the ends of the sheet, wherein binding processing is possible for a large number of sheets and the problems of paper jams due to inclining or poor alignment are solved and which has a small size, is low in cost and is highly reliable. In order to achieve the above object, a typical configuration of the sheet processing apparatus of the present invention comprises: a conveyance portion which conveys sheets; an intermediate stacking portion which temporarily stacks sheets conveyed from the conveyance portion; and a binder which performs a binding process for binding the sheets stacked in the intermediate stacking portion, and the binder is fixed at one side of the intermediate stacking portion and the sheet which is conveyed from the conveyance portion passes the opening of the binder and is stacked in the intermediate stacking portion; the conveyance portion comprises a plurality of drive rollers in the direction that intersects the conveyance direction; and the drive rollers other than the drive roller that is closest to the binder form conveyance roller pairs with driven rollers.
