Abstract

PURPOSE:To form a toner image on a photoconductor layer without corona charging, by bringing the photoconductor layer and a toner layer into contact with each other and exposing an image while applying an electric field. CONSTITUTION:A magnetic roller 5 holding a toner 13 as a layer 4 is brought into contact with a photosensitive drum 20, and a voltage 9 is applied between them. The image is exposed to a photoconductor layer 1 through a transparent supporting material 3 and a transparent electrode of the drum by a light emitting diode array 6 on the inside of the drum. A current is flowed to a part, which is irradiated with the light, of the photoconductor layer 1, and the toner in the toner layer 4 in this part is charged and is transferred to the surface of the photosensitive drum 20 by the electrostatic force. This toner image 17 is transferred to copy paper 18. Since the toner on the photosensitive drum 20 including the toner which is not transferred and the remainder is recovered into the toner layer 4 on the magnetic roller 5, a cleaning means is unnecessary.
