Provided that a process for manufacturing an elastic roller having a mandrel and a coating film. The process comprise a first step of forming a coating film on an outer peripheral surface of a first mandrel, and a second step of forming a coating film on an outer peripheral surface of a second mandrel. The process further comprises a cleaning step between the steps. The cleaning step comprising: making a cleaning member arranged coaxially with the central axis of a circular coating head, in a downstream side in a moving direction of the first mandrel with respect to the circular coating head, making the cleaning member relatively approach the circular coating head; bringing a surface to be cleaned into contact with the cleaning member; rotating the cleaning member while the surface comes in contact with the cleaning member; and inserting the cleaning member into the center hole.

Process for manufacturing elastic roller, and coating apparatus

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.
