摘要： A charge roller includes a core, a resistive layer disposed on a circumferential surface of the core to charge an image-bearing member without contact, and gap members formed of tape-shaped films. These films are fixed to both ends of the charge roller by winding each of the films in a direction opposite a rotational direction of the charge roller in use and perpendicular to the axial direction thereof to form n layers (wherein n≧2) extending in the axial direction at every position in the circumferential direction of the charge roller. The gap members are pressed against a circumferential surface of an image-bearing member to define a charge gap between the image-bearing member and the charge roller.

A bias applying apparatus applies a bias voltage to move the toner of the image carrier cleaning member to the image carrier. An endless transfer member cleaning blade removes toner adhering to the endless transfer member after the toner image of the endless transfer member is transferred to a transfer material while abutting against the endless transfer member. The following relationship is satisfied: cleaning recovery member width
