Abstract

Provided is a member for electrophotography that is not reduced in charge-providing performance even by its long-term storage and use under a high-temperature and high-humidity environment, and is hence conducive to the formation of a high-quality electrophotographic image. The member for electrophotography includes: an electroconductive substrate; and an electroconductive layer, in which: the electroconductive layer contains a resin having a cationic organic group in a molecule thereof and an anion; a total sum of contents of an alkali metal and an alkali earth metal in the electroconductive layer is 500 ppm or less; and the anion includes at least one selected from the group consisting of a fluorosulfonate anion, a fluorocarboxylate anion, a fluorosulfonylimide anion, a fluorosulfonylmethide anion, a fluoroalkylfluoroborate anion, a fluorophosphate anion, a fluoroantimonate anion, and a fluoroarsenate anion.
