Charging member, process cartridge, and electrophotographic device |
| abstract |
The present invention relates to a charging member. The charging member comprises an electro-conductive substrate and an electro-conductive surface layer, wherein the surface layer includes a binder resin, an electro-conductive particle dispersed in the binder resin, and a resin particle that roughens the surface of the surface layer; the surface layer has a plurality of protrusions each derived from the resin particle in the surface thereof; the resin particle that forms the protrusion has a pore inside thereof; has a porosity Vt of porosity is 2.5% by volume or less as a whole; and has a region whose porosity V11 is 5% by volume or more and 20% by volume or less, wherein the region is farthest away from the electro-conductive substrate in the resin particle, and assuming that the resin particle is a solid particle having no pores, the region corresponds to a 11% by volume-occupying region of the solid particle. |
