Charging device and image forming apparatus

摘要

A charging device for electrically charging a photosensitive member includes: a charging member for electrically charging the photosensitive member by being supplied with a voltage; and a supporting member for supporting the charging member so as to press-contact to the photosensitive member. The charging member includes: an electroconductive support; an elastic base layer supported by the electroconductive support; and an elastic surface layer, provided on a surface of the elastic base layer, being harder than the elastic base layer. The elastic surface layer is provided with projected portions and recessed portions. The projected portions are elastically deformable in contact with the photosensitive member, leaving electrically dischargeable gaps between the recessed portions of the elastic surface layer and the photosensitive member.
