PURPOSE:To electrify a photosensitive material by a low voltage without generating zone, by employing a conductive brush electrifier as the electrifier of a process unit. CONSTITUTION:The process unit 10 is constituted of a conductive base member 2b in which the conductive brush electrifier is fixed on a unit case 3, and a conductive brush 2a mounted linearly from the member 2b. And a voltage of around several hundred V - 2,000V is supplied from the power source of a main body to the conductive brush electrifier at the time of printing via a power supplying parting the unit 10, and a photosensitive drum 1 is electrified at desired uniform electrified potential. Therefore, no ozone is generated at the time of electrification.
