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： When a polymer blend of an NBR and an alkylene oxide-polymerized polymer is used as the electro-conductive elastic layer of an electro-conductive member for electrophotography, a change in shape of the electro-conductive member occurs owing to its expansion due to water absorption, thereby causing image unevenness in some cases. In addition, when the ratio at which the alkylene oxide-polymerized polymer is blended is reduced for suppressing the shape change due to water absorption, image unevenness resulting from the insufficiency of electro-conductivity occurs in some cases. When an electro-conductive member for electrophotography having an electro-conductive elastic layer containing an NBR to which a specific alkylene oxide oligomer is graft-bonded is used, high ionic electro-conductivity is obtained and a change in its shape due to water absorption is reduced.
