Abstract:
The present invention provides an electrophotographic member having excellent deformation recovery even when stored or used under a high temperature and high humidity environment, which is useful in forming a high-quality electrophotographic image; a process cartridge; and an electrophotographic apparatus. The electrophotographic member of the present invention includes a conductive mandrel and an electro-conductive layer; the electro-conductive layer including a resin synthesized from an ion conducting agent and a compound being able to react with the ion conducting agent; the ion conducting agent including a specific anion and a cation having at least three hydroxyl groups; the compound being able to react with the hydroxyl group.
