Abstract:
1. A charging device configured to electrically charge a rotatable photosensitive member, comprising: a first charging member formed by winding a base material, which is provided with conductive fibers in a brush-like form, around an outer peripheral surface of a core material, the first charging member being rotatable while the conductive fibers contact the photosensitive member; a second charging member formed by winding a base material, which is provided with conductive fibers in a brush-like form, around an outer peripheral surface of a core material, the second charging member being rotatable while the conductive fibers contact the photosensitive member, at a position located downstream of the first charging member in a rotation direction of the photosensitive member; and a driving mechanism configured to rotationally drive the first charging member and the second charging member so that, when the first charging member and the second charging member electrically charge the rotating photosensitive member, a region on a surface of the photosensitive member facing a seam, which is formed by mutually adjacent edges of the base material of the first charging member at a contact part between the first charging member and the photosensitive member, is not superposed on a region on the surface of the photosensitive member facing a seam, which is formed by mutually adjacent edges of the base material of the second charging member at a contact part between the second charging member and the photosensitive member.
