写真装置。[Scope of Claim for Utility Model Registration] A rotatable photosensitive drum having a photoconductive layer and a conductive layer on its outer peripheral surface, charging means for charging the photosensitive drum, and charging means disposed in sequence around the photosensitive drum, and charging an exposure unit that exposes the photosensitive drum to form a latent image on the surface of the photosensitive drum; a developing unit that develops the latent image with fine particles; a transfer unit that transfers the developed image onto recording paper; In an electrophotographic apparatus equipped with a static eliminator, the static eliminator repeatedly removes static electricity from the photosensitive drum a predetermined number of times after the transfer of the developed image is completed and before the photosensitive drum is charged for the next image. An electrophotographic apparatus characterized in that it is provided with static elimination repetition means.
