An electrically conductive member for electrophotography is provided which has an electrically conductive mandrel and an electrically conductive layer on the peripheral surface of the mandrel; the electrically conductive layer containing a binder resin having as an ion exchange group a sulfo group or a quaternary ammonium salt group in the molecule and an ion with a polarity opposite to that of the ion exchange group; the binder resin further having any structure selected from the group consisting of structures represented by formulas (1)-1 to (1)-3, and any structure selected from the group consisting of structures represented by formulas (2)-1 and (2)-2, and having a molecular structure that prevents any matrix-domain structure from being formed in the electrically conductive layer. |
