<P>PROBLEM TO BE SOLVED: To provide a conductive roll which is made compact and light in weight, is excellent in durability and sliding performance and is reduced in resistance variation against energization and environment, and to provide a cleaning unit, a process cartridge and an image forming apparatus using the conductive roll. <P>SOLUTION: The cleaning roll 10 (the conductive roll) is composed of: a core body 12 covered by a covering layer 11; and a shaft 13 installed along a central axis of the core body 12. The coating layer 11 contains bismaleimide resin and a conductive agent. The cleaning roll 10 is utilized in the cleaning unit, the process cartridge and the image forming apparatus. <P>COPYRIGHT: (C)2009,JPO&INPIT |
