Abstract
Provided is an electrophotographic member which hardly undergoes deformation even when subjected to a load over a long period of time under a high-temperature and high-humidity environment and thus can stably form a high-quality electrophotographic image. The electrophotographic member includes: an electroconductive substrate; and an electroconductive resin layer on the substrate, in which the resin layer contains a cation having a specific structure and a specific anion.
