Abstract
A developing member includes a conductive substrate, a conductive elastic layer on the conductive substrate, and a plurality of insulating domains on the conductive elastic layer, wherein the surface of the developing member includes the surfaces of the insulating domains and an exposed portion of the conductive elastic layer not covered with the insulating domains. The conductive elastic layer contains a resin and an anion, wherein the resin has a specific cationic structure synthesized from an ion conductive agent composed of a cation including at least one reactive functional group and an anion and a compound that can react to the ion conductive agent.
