    摘要： The present invention provides a charging roller having a stable chargeability and capable of preventing occurrence of “fogging” on an electrophotographic image. The invention relates to a contact-charging type charging roller which includes a conductive support and a surface layer. The surface layer contains a binder, resin particles containing a carbon black dispersed in the binder, and graphitized particles dispersed in the binder; and the surface layer has, on its surface, convex portions derived from the resin particles, and convex portions derived from the graphitized particles. These convex portions have a specific relationship.

    摘要： Concerned with a charging member in the conductive surface layer of which the conductive particles are so kept from agglomerating as to make charging performance not easily change even where the surface layer expands and contracts repeatedly in various environments. The charging member is a charging member having a conductive substrate and formed on the substrate a conductive elastic layer and a conductive surface layer. The elastic layer contains a polymer having a unit coming from ethylene oxide, and the surface layer contains a binder resin and graphitized particles. The binder resin contains a resin having in the molecule a urethane linkage or a siloxane linkage, or a urethane linkage and a siloxane linkage, and the graphitized particles have a graphite (002) plane lattice spacing of from 0.3362 nm or more to 0.3449 nm or less.
