Abstract
A used developer-carrying member having a resin coating layer on a substrate is regenerated through a step of scraping the resin coating layer of the used developer-carrying member to form a developer-carrying member surface having unevenness showing a central line-average roughness Ra of at most 0.8 &mgr;m, and a step of coating the developer-carrying member surface having the unevenness with a coating layer of a resinous composition comprising at least a binder resin and electroconductive fine powder. The regenerated developer-carrying member can be reinstalled in a developing apparatus and subjected to repetitive electrophotographic image forming cycles.
