Abstract:
A sheet discharge processing device for sequentially discharging sheets, conveyed through image forming means for forming images on the sheets on the basis of image data, onto a discharge tray with image-bearing surfaces facing up or down, comprising:a straight convey path for discharging sheet conveyed through the image forming means onto a first discharge tray, with image-bearing surfaces facing up, such that the sheets are stacked sequentially on each other from a last page;a reverse convey path for discharging the sheets conveyed through the image forming means onto a second discharge tray located substantially parallel to the first discharge tray, with image-bearing surfaces facing down, such that the sheets are stacked sequentially on each other from a start page, said reverse convey path branching from said straight convey path;reversing-biasing means, placed on said reverse convey path, for applying an external force to a rear surface of a sheet to reverse and discharge the sheet onto the second discharge tray;switching means for switching a convey route of a sheet to said straight convey path or said reverse convey path; andcontrol means for controlling said switching means and said reversing-biasing means depending on whether an image-bearing surface of a sheet conveyed through the image forming means faces in a first direction and a second direction which is parallel and opposite to the first direction.
