Abstract
The present invention provides an electrophotographic member in which an increase in resistance is small even in use at low temperature and which contributes to the formation of a high quality electrophotographic image, and a process cartridge and an electrophotographic apparatus using this electrophotographic member as a charging member or a developer carrying member. Therefore, the electrophotographic member of the present invention is an electrophotographic member including an electro-conductive mandrel and an electro-conductive layer, wherein the electro-conductive layer includes a urethane resin and an ion-conductive agent, the urethane resin has, between two adjacent urethane bonds, a structure represented by formula (1) and at least one structure selected from the group consisting of a structure represented by formula (2) and a structure represented by formula (3), and the ion-conductive agent contains a particular anion.
