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.
