An electrophotographic member that contributes to the formation of a high-quality electrophotographic image with little increase in resistance when energized over a long period of time in a high-temperature and high-humidity environment, and an electrophotographic member as a charging member and / or developer carrier. Of a process cartridge and an electrophotographic apparatus having a member for use. An electrophotographic member having a substrate and a conductive layer, the conductive layer, a resin having a structural unit represented by the following structural formula (1), a fluorinated sulfonylimide anion, and a sulfonyl fluoride methide From anion, fluorinated sulfonate anion, fluorinated carboxylate anion, fluorinated borate anion, fluorinated phosphate anion, fluorinated arsenate anion, fluorinated antimonate anion, dicyanamide anion, bis (oxalato) borate anion An electrophotographic member containing at least one selected anion. In the structural formula (1), R1 represents a hydrogen atom or a methyl group, and Z represents a cationic organic group. [Selection figure] None |
