PURPOSE:To omit a destaticizing eraser, to improve reliability, maneuverability and image quality and to reduce the size of a device by arranging a brush charger immediately after a cleaner part and contacting and rubbing the surface of a photosensitive body with the tip of the brush to uniformly charge the surface of the photosensitive body. CONSTITUTION:The cleaner 6, the brush charger 2, an exposure part 3, a developing device 4, a transfer charger 5, etc., are arranged on the periphery of the photosensitive drum 1 having photoconductive layers laminated on the outer periphery of an aluminium pipe (conductive material). The brush charger 2 consists of high resistance rayon fiber bundle obtained by dispersing conductive carbon grains and the surface of the conductive body 1 is rubbed by the tip of the fiber while impressing a constant voltage to the fiber bundle, so that the surface of the photosensitive body is charged with uniform potential. An eraser constituted so as to execute light irradiation and destaticization by the lamp can be omitted, various troubles to be generated by using the eraser can be resolved, the reliability, maneuverability and image quantity can be reduced and the size of the device can be reduced.
