ABSTRACT:
An image forming apparatus provided with a mechanism for discharging the sheet which has been image-processed. The sheet supplying station accommodating a cassette or the like and the image forming station containing a photosensitive member or the like are substantially vertically aligned. The apparatus comprises a sheet reversing and discharging mechanism for inverting the face orientation of the sheet and then discharging it. The sheet reversing and discharging mechanism has a sheet switch-back passage which is disposed between the sheet supplying station and the image forming station, the sheet switch-back passage extending substantially horizontally. Additionally, the apparatus includes a device for selectively shifting the discharged sheets so as to form groups of sheets, without disturbing already-formed groups.
