Abstract
PURPOSE:To eliminate unnecessary charging by a charger which operates during turning of photosensitive drum with a simple constitution by letting the destaticizing lamps provided to exposure optical system light at the resetting of original base. CONSTITUTION:Lamps 20, 20 are mounted to a lens plate 18 which is provided with lens 3 for projection of exposure light by the original exposure lamps 2, 2 in a dark box. These lamps 20, 20 are lighted by way of the driving device of the copying machine to radiate a drum 6 at the resetting of an origignal base 1. Then, charging of the portions having no relation to latent image formation of the drum 6 by a charger 7 which is normally in an operating state during revolution of the drum 6 is removed with the simple constitution, whereby the burden of the developing device 8 may be reduced.
