An electrophotographic apparatus comprising a corona charger, a photosensitive and electrostatic-charge retentive drum including an electrically conductive substrate and a photosensitive layer having a narrower width than that of a record paper, and a screening member inserted between the corona charger and a peripheral part of the photosensitive and electrostatic-charge-retentive member for gradually decreasing a quantity of electrostatic charge charged at side edge portions of the photosensitive layer in a direction toward the side edges of the photosensitive layer, whereby black line and stripe can be prevented from appearing along the side edges of the record paper.
