Abstract

Provided is an electrophotographic member that has a high excessive charging-suppressing effect under a low-temperature and low-humidity environment, and has high charge-providing performance under a high-temperature and high-humidity environment, and a process cartridge and an electrophotographic apparatus each including the electrophotographic member. The electrophotographic member is an electrophotographic member including an electro-conductive substrate and an electro-conductive resin layer, the electro-conductive resin layer contains a cation and at least one anion selected from the group consisting of anions represented by the following formulae (1) to (5): where X represents an arbitrary halogen atom, n in the structural formula (4) represents an integer of from 2 to 6, and n in the structural formula (5) represents an integer of 2 or 3.
