Abstract

A sheet conveyed into a sheet discharge processing device is conveyed through a straight convey path by first convey rollers and then is discharged onto a first discharge tray by second convey rollers and first discharge rollers. Second discharge rollers are arranged on a reverse convey path. A second discharge tray and a fan for applying an external force to the rear surface of a sheet are placed below the reverse convey path. When the trailing end of a sheet is detected by a second detection sensor, the fan is driven for a predetermined period of time to blow air against the rear surface of the discharged sheet. When sheets conveyed into the sheet discharge processing device are guided to a post-processing convey path by the first convey rollers so as to be subjected to post-processing, and are sequentially conveyed to a sheet storing section by convey rollers from the last or start page, the sheets are guided along one of guide plates constituting the sheet storing section to be aligned. A stapler for stapling a bundle of sheets aligned in the sheet storing section is placed below the sheet storing section.
