摘要： An image forming apparatus includes an endless transfer member and a plurality of image forming units. The endless transfer member is arranged at a transverse position in the image forming apparatus, and has a circulatory rotating surface declining at a predetermined angle to a horizontal plane. Each of the plurality of image forming units includes a first surface facing the endless transfer member and a second surface opposite to the first surface and angled in a similar direction to the endless transfer member. The plurality of image forming units perform an image forming operation and are arranged next to one another facing the endless transfer member such that, in any two adjacent image forming units of the plurality of image forming units, one of the any two adjacent image forming units has a portion overhanging the other one of the any two adjacent image forming units.

摘要： A charging member, which can be provided in a process cartridge and/or in an image forming apparatus, includes a conductive supporting member, an electrical resistance control layer formed on an outer circumferential surface of the conductive supporting member, and a nonconductive gap retaining member configured to retain a gap between the conductive supporting member and an image carrying member closely disposed to each other to have a constant distance. At least a portion of the nonconductive gap retaining member is mounted on the electrical resistance control layer at both ends of the conductive supporting member, and a circumference of the nonconductive gap retaining member projects from the electrical resistance control layer. An amount of projection of the gap retaining member from the electrical resistance control layer decreases as the gap retaining member tapers in a direction toward a center of an image formation region.
