Abstract: PURPOSE:To prevent developer from adhering to second and succeeding electrifying means by providing a maximal value on an upstream side in the rotating direction of an image carrier in corona current distribution toward an image carrier by the 2nd and succeeding electrifying means. CONSTITUTION:When impressed voltage on the shield 5b of a re-electrifier 5 by an external power source is the same as the potential of a negative toner layer on a photoreceptor 1 after re-electrification or above it, electric field in the same direction as the electric field generated by a corona wire is generated so as to prevent toner from reversely flying to the shield 5b of the re- electrifier 5. However, when the impressed voltage on the shield 5b of the re- electrifier 5 is made too large, carrier adhering to a 1st laser non-irradiation part and the positive toner reversely electrified in a 1st latent image on the photoreceptor 1 are allowed to fly to the shield 5b of the re-electrifier 5 at a part close to the photoreceptor 1. By moving the maximal value in the corona current distribution to a side near to the shield 5b of the re-electrifer 5 on the upstream side in the rotating direction of the photoreceptor 1, the shield 5b of the re-electrifier 5 and a grip 23 are prevented from being soiled by toner because of the reverse flying.
