ABSTRACT:
A paper stacking control device for use in an electrophotographic copier, printer, facsimile apparatus or similar image forming apparatus having a paper transport path for temporarily stacking paper sheets each carrying an image on one surface thereof on an intermediate tray. A paper sheet being transported by belts which face the intermediate tray is retained by the pawls of coactive rotatable disks and then stacked on the intermediate tray while being turned over due to the rotation of the disks. The paper sheet stacked on the intermediate tray is restrained by paper pressers at a portion thereof adjacent to the leading edge or the trailing edge and is thereby prevented from being displaced in the stacked position.
