Abstract:
1. An image forming system comprising: an image forming device which forms an image based on image data processed in a unit of page, and prints, on a paper, the formed image to discharge the printed paper; a finisher which, in a case where stapling of a plurality of printed papers is requested in a print job given to said image forming device, holds the printed papers, which are discharged from said image forming device, on a stacker and staples a bundle of the printed papers held on the stacker to discharge the stapled bundle to a tray; a storage unit which stores a value of an upper limit number of printed papers that are staplable in said finisher; and a controller which, in a case where the stapling in said finisher is requested in the print job given to said image forming device, counts the number of image data processed in a unit of page in the current print job in order in which the image data are processed, while the image data processed in a unit of page are supplied to said image forming device in order in which the image data are processed, and when determining that a pre-stage count value which is a value of the counted number is equal to the upper limit number and the pre-stage count value will exceed the upper limit number if the next image data is processed, performs control in which the bundle held on the stacker is discharged to the tray without being stapled in said finisher, before the controller processes the next image data and as a result, the pre-stage count value actually exceeds the upper limit number, thereby making the number of the printed papers discharged without being stapled by said finisher smaller than the upper limit number.
