Abstract:
The present invention provides an electrophotographic electrically conductive member in which conductivity needed for a charging member is secured, and defects in an image attributed to uneven discharging can be minimized independently of a long-term use and an environment of use. An electrophotographic electrically conductive member comprising an electrically conductive support and an electrically conductive layer, wherein the electrically conductive layer includes an ion conductive resin having a quaternary ammonium ion in a molecule structure as a binder resin, and a carrier molecule represented by the following formula (1) or (2): (wherein n1 and n2 each independently represent an integer of 1 to 4).
