A charging device includes a corona charger (2), provided with an opening opposing a photosensitive member (1), for electrically charging the photosensitive member; a sheet-like member (10) provided so that the sheet-like member can cover the opening; a movable device (12) for moving the sheet-like member; and a regulating device (16,17) for regulating a shape of the sheet-like member so that a central portion of the sheet-like member protrudes toward the corona charger with respect to a circumferential direction of the photosensitive member. |
