Abstract

Provided is an electroconductive member for electrophotography in which movement of a quaternary ammonium salt toward the surface of a binder resin is suppressed and which exhibits a less reduction in electroconductivity through electrification. The electroconductive member for electrophotography comprises an electroconductive shaft core and a resin layer, and the resin layer comprises a binder resin and at least one selected from quaternary ammonium salts having structures represented by the formulae (1) to (8).
