Abstract:
The present invention directs to provide a charging member having a protrusion to which smear is difficult to adhere even in a long-term used, and as a result being capable of exhibiting stable charging performance. The charging member has an electro-conductive substrate and an electro-conductive surface layer, wherein the surface layer includes a binder resin and a resin particle including a plurality of electro-conductive domains inside thereof, the surface layer has a protrusion derived from the resin particle, and the electro-conductive domains are localized in the vicinity of the surface of the resin particle.
