摘要：
The present invention provides a conductive member in which it is possible to control a variation in resistance due to physical stress from a contact member, and an uneven density in a halftone image can be prevented.The conductive member is a development roller which includes a conductive shaft core, a conductive elastic layer, and a conductive surface layer. The conductive elastic layer contains silicone rubber and a basic carbon black dispersed in the silicone rubber. The surface layer contains a urethane resin having a carboxyl group in its molecule and an acidic carbon black dispersed in the urethane resin.
