Abstract
Provided is an electrophotographic member that shows a small increase in electrical resistance value even when used under a low-temperature environment. The electrophotographic member is an electrophotographic member including an electroconductive substrate and a resin layer on the electroconductive substrate, wherein the resin layer contains an anion, inorganic particles having a hydrophobicity degree of 40% or more and 80% or less, and a resin having a specific cation structure.
