Abstract:
To provide an electrically conducting member for electrophotography which can not easily come to change in electrical resistance value even upon application of direct current and also has made any ion conducting agent kept from bleeding. The electrically conducting member has an electrically conducting substrate and an electrically conducting layer; the electrically conducting layer containing an epichlorohydrin rubber having in the molecular structure at least an alkylene oxide (AO) unit, an epichlorohydrin (ECH) unit and a unit having a sulfonate ion; the AO unit being at least one unit of an ethylene oxide unit, a propylene oxide unit and a butylene oxide unit; and the AO unit(s) in the rubber being in a content of 5 to 60% by mass in total and the ECH unit in the rubber being in a content of 30% by mass or more.
