Abstract
The present invention provides a highly electro-conductive electrophotographic member which contributes to formation of high-quality electrophotographic images while bleeding out of an ion conducting agent is reduced, a process cartridge, and an electrophotographic apparatus. Accordingly, the electrophotographic member according to the present invention includes an electro-conductive mandrel and an electro-conductive layer, wherein the electro-conductive layer contains a resin synthesized from a nitrogen-containing aromatic heterocyclic cation and a compound being able to react with the nitrogen-containing aromatic heterocyclic cation, and an anion; the nitrogen-containing aromatic heterocyclic cation has two substituents bonded to hydroxyl groups; and the substituent bonded to the hydroxyl group is bonded to a nitrogen atom of a nitrogen-containing aromatic heterocycle of the nitrogen-containing aromatic heterocyclic cation.
