Summary:PURPOSE:To prevent toner from sticking to an end block and to prevent a charger part from being stained by covering the photosensitive body side of the end block with conductive members and earthing those conductive members. CONSTITUTION:The side of the photosensitive body 11 of the end block 31 is covered with a metallic plate 35, its end block is attached to a casing 30 with screws 36 and the metallic plate 35 is earthed. For instance, if the toner is negatively electrified and a transferring and separating charger part 15 positively discharges, the end block 31 is positively electrified. But it is covered with the metallic plate 35, so that the electrostatic attraction of the end block 31 does not act on scattering toner. Therefore, the toner scattering from a developing part 14 and a cleaning part 16 is not attracted to the end block 31. Thus, toner sticking to the end block and the stain of the charger part can be prevented.
