Abstract

PURPOSE:To let the potentials of photoreceptor become substantially even when the revolution stops by stopping all the chargings except AC charging prior to the stopping of the drum and stopping the entire surface of the drum in a state where no charges are left through AC charging. CONSTITUTION:This comprises forming electrostatic latent images on the photoreceptor while revolving a rotary photosensitive drum 1, processing the latent images thereof to form visible images on transfer material and removing the residual images, wherein the image formation is operated and executed, thence the 1st corona discharging means 9 having the charging action having operated till then is disabled and the 2nd corona discharging means 10 having destaticizing action is operated and is used as a means for evening the photoreceptor, after which the revolution of the revolving photoreceptor 1 is continued until the photoreceptor surface which had opposed to the first corona discharging means 9 when said corona discharging means was disabled reaches at least the 2nd corona discharging means, so that during its revolution the non-operation state of the 1st corona discharging means 9 and the operation state of the 2nd corona discharging means 10 are maintained.
