The charging device includes an electroconductive member which directly contacts the photosensitive member surface to charge the photosensitive member surface. The electroconductive member forms a nip width with the photosensitive member of at least 0.5 mm and a load per unit contact area between the electroconductive member and photosensitive member is between 0.5-30 g/mm.sup.2. With respect to the longitudinal direction of the photosensitive member, the width of the photosensitive member surface cleaned by the cleaning device is equal to or greater than the width of the photosensitive member surface contacting the electroconductive member.

摘要： There is provided a charging member comprising an electroconductive substrate, and an elastic layer, an electroconductive layer and a resistance layer disposed in this order on the substrate. Such charging member provides good contact with a photosensitive member, to provide good image quality without causing an image defect such as white spot based on charging unevenness. Further, the charging member causes no leak even when the photosensitive member has a pin hole, and reduced the level of noise based on an AC voltage to be applied thereto.
