摘要： A blade-like charging member for charging a surface of an image bearing member. The blade-like charging member includes a charging portion for effecting electric discharge to the surface of the image bearing member and a non-charging portion. The non-charging portion can contact the image bearing member with a gap. At least a part of the non-charging portion is made of a material having a higher resistance than that of the charging portion so as to prevent electric discharge between the non-charging portion and the surface of the image bearing member. The non-charging portion is capable of sliding contact with the surface of the image bearing member over the entirety of an image forming region width of the surface of the image bearing member. The charge portion and the non-charging portion are bonded to each other by adhesive material at a connection interface.

摘要： A charging device includes a charging roller, a drive transmission device, and a charging roller cleaner. The charging roller opposes an image carrier driven to rotate and rotates to charge the image carrier. The charging roller cleaner contacts the charging roller to clean the charging roller. The drive transmission device transmits torque from the image carrier to the charging roller, and includes an image carrier gear and a driven gear. The image carrier gear and the driven gear form a gear train to drive the charging roller in response to rotation of the image carrier. The charging roller cleaner is disposed facing a rear surface of the charging roller to prevent displacement of the charging roller due to a force generated by a pressure angle formed between the image carrier gear and the driven gear when the charging roller rotates in response to rotation of the image carrier.

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.
