PURPOSE:To achive excellent copying image with a simple constitution, by making toner image copying via stylus electrodes provided opposingly to a copying section of a photoreceptor drum. CONSTITUTION:An electrode stand 8 providing stylus electrodes 11... in opposition to a photoreception drum 1 is provided, and at the toner image copying, the stand 8 moves through solenoids and the electrodes 11... slide on the back side of a copying paper 5. When plasma charges are applied to the electrodes 11..., positive ions only are moved and attached to the paper 5 with electric field and a negative toner image is copied from the drum 1. With this simple constitution, the functions of advantages of the corotron method and the bias roll method are played. Since the electrodes 11... are directly contacted, the copying voltage can be lower, and the electrodes 11... are directly contacted, the copying voltage can be lower, and the electrodes 11... are well adhered to the copying paper with elasticity. Thus, excellent roner image copying can be made without unevenness. |
