Abstract
PURPOSE:To prevent occurrence of black streak in copying machine or the like and increase the cleaning performance, by separating the transfer paper from the photoreceptor by means of corona generator, and changing the corona discharge quantity to destaticize the photoreceptor. CONSTITUTION:When destaticizing a photosensitive drum 1, a voltage E1 is applied; when separating the transfer paper, a proper voltage E2 is applied to a corona charger 6. Accordingly, an AC power source 13 raises to a specified voltage by means of a transformer 17, and a DC power source 14 is constituted with a varistor 18 and a diode 19. When destaticizing the photoreceptor 1, a contact 20 is set to ON and a contact 21 OFF by means of a control circuit 15, so that the secondary side of the transformer 17 is grounded. When separating the transfer paper, the contact 20 becomes ON, and the contact 21 OFF, so that a positive voltage is applied by the varistor 18 and diode 19. Since the separation of the transfer paper and destaticizing of the photoreceptor are carried out by varying the discharge quantity of the corona generator, occurrent of black streaks may be prevented.
