Abstract:
An electrophotographic member is provided in which conductivity barely reduces and sufficient conductivity is obtained even under a low temperature and low humidity environment, a reduction in resistance beyond necessity is readily suppressed even under a high temperature and high humidity environment, and the bleeding of the quaternary ammonium salt can be suppressed. There is provided an electrophotographic member including an electroconductive mandrel and an electroconductive layer, wherein the electroconductive layer includes a resin having at least one of a structure represented by the following formula (1) and a structure represented by the following formula (2) in the molecule, and an anion:
