ABSTRACT:
A sheet discharging apparatus has a plurality of trays for receiving sheets from an image forming apparatus and discharge rollers corresponding to the respective trays. The discharge rollers are rotatable in forward and reverse directions. The sheet discharging apparatus has a transport path for connecting the trays and a sheet discharge opening of the image forming apparatus. A gate for switching the destinations of sheets is disposed at each branched point in the transport path. A selected tray for finally receiving sheets is selected from the trays, and a temporary tray is selected from the trays other than the selected tray. A sheet is temporarily fed in a non-reversed state to the temporary tray from the image forming apparatus. Then, by rotating the discharge rollers in the reverse direction, the sheet is discharged in a reversed state to the selected tray from the temporary tray. A tray which can efficiently execute reverse discharge processing is appropriately specified according to the selected tray. It is thus possible to discharge sets of sheets with their image-formed side facing downward in page order without using a special switchback mechanism or decreasing the sheet output speed from the image forming apparatus.
