Abstract

Provided is an electrophotographic member capable of forming a high-quality electrophotographic image. The electrophotographic member includes an electroconductive substrate and an electroconductive resin layer on the electroconductive substrate, in which the electroconductive resin layer contains a resin having, in the molecule, a specific cation structure, and a specific anion.

an anion, and
wherein the anion comprises at least one selected from the group consisting of a fluorinated sulfonylimide anion, a fluorinated alkylsulfonylimide anion, a fluorinated sulfonyl methide anion, a fluorinated alkylsulfonyl methide anion, a fluorinated sulfonate anion, a fluorinated alkylsulfonate anion, a fluorinated carboxylate anion, a fluorinated borate anion, a fluorinated phosphate anion, a fluorinated arsenate anion, a fluorinated antimonate anion, a dicyanamide anion, and a bis(oxalato)borate anion:

in the formulae (1) to (4):
R1 to R8 each independently represent a hydrocarbon group needed for a nitrogen-containing heterocycle in each of the formulae (1) to (4) to form a five-membered ring, a six-membered ring, or a seven-membered ring;
R9 and R10 each independently represent a hydrogen atom or a hydrocarbon group having 1 or more and 4 or less carbon atoms; and
