ABSTRACT:
The present invention relates to a developer carrying member for carrying a developer having at least a substrate and a resin-coated layer formed on the surface of the substrate. The developer carrying member is the one which carries a one-component developer to visualize the electrostatic latent image carried by the electrostatic latent image carrying member, the resin-coated layer contains at least a binder resin, graphitized particles and roughing particles, the graphitized particles has 0.20 to 0.95 of graphitization degree (p (002)), and wherein in the surface configuration of the resin-coated layer as measured by use of focusing optical laser, the volume (B) of a microtopographical region defined by a certain area (A) of the microtopographical region without convexity formed by the roughing particles meets the following relationship 4.5≦B/A≦6.5, and the resin-coated layer has 0.9 to 2.5 μm of arithmetic mean roughness (Ra).
