Abstract

PURPOSE:To have a small-sized image forming device, which offers unlimited number of sheets to be accumulated and possibility of discharging the electricity, by furnishing a deelectronizing needle for discharge of the sheet at the upper part of a sheets classifying tray. CONSTITUTION:Deelectronizing needles 20, 21, 22 remove the electricity which charges the sheets loaded on a sheets handling arrangement, where delivery rollers 2, 3 send eash sheet under guidance of guides 1, 1 into a tray 4 supported by a tray support 5 covered with a tray support cover 19. Thus the sheet can be prevented from being drawn to over the tray support 5.
