1. An electrophotographic photosensitive member which comprises a support, a conductive layer formed on the support, an intermediate layer formed on the conductive layer, and a photosensitive layer formed on the intermediate layer, wherein;

  • said conductive layer is a layer formed by using a conductive layer coating fluid which contains (a) TiO2 particles coated with oxygen deficient SnO2 (P) having an average particle diameter of from 0.20 μ

    m or more to 0.60 μ

    m or less and (b) a binding material (B), wherein a mass ratio of (P);

    (B) is from 2.3;

    1.0 to 3.3;

    1.0; and

    said conductive layer has a volume resistivity of from more than 8.0×

    108 Ω

    cm to 1.0×

    1011 Ω

    cm or less.
