ABSTRACT:
A paper refeeding device incorporated in an image forming apparatus for temporarily stacking paper sheets each coming out of an image forming section and carrying an image on one side on a refeed tray and, then, refeeding the paper sheets to the image forming section. An air velocity switching mechanism causes an air knife to blow air at a breeze velocity or a zero velocity which does not lift the paper sheets stacked on the refeed tray, until more than a predetermined number of paper sheets have been discharged by discharge rollers and stacked on the refeed tray.
