A rubber composition for a conductive roller that has at least an elastic layer above an outer periphery of a shaft member having conductivity is provided, the rubber composition including: a binary epichlorohydrin rubber; and a vulcanizing agent that contains at least sulfur, wherein the rubber composition does not contain a quinoxaline vulcanizing agent and a triazine vulcanizing agent.

Epichlorohydrin composition for conductive roller, conductive roller, charging unit, image forming apparatus, process cartridge, and method of manufacturing conductive roller

An electro-conductive roll is provided that makes contact with a body to be charged in a state in which a voltage is applied thereto, and charges the body to be charged, a surface of the electro-conductive roll satisfying the following conditions (a) and (b):

Electro-conductive roll and image-forming apparatus using the same

A developing machine and a developer carrier therefor, for visualizing an electrostatic latent image formed on an electrostatic latent image carrier by adhesion of a developer which is carried while adhering on the surface of the developer carrier and given electric charge by triboelectricity. The developer carrier has a resin surface layer containing a charge-imparting agent selected from the group consisting of an iron complex, a basic amino acid, a polyamide fine powder, and a stearic acid salt.
