Patent ID: 8524430

Claim:
An electrophotographic photosensitive member, comprising: a conductive support; a conductive layer containing conductive particles having a volume-average particle diameter of 0.1 μm or more; an intermediate layer; and a photosensitive layer, the conductive layer, the intermediate layer, and the photosensitive layer being provided on the conductive support in the stated order, wherein the conductive layer contains a polyolefin resin having the following repeating structural units (A1), (A2), and (A3), and a mass ratio (%) of the units (A1), (A2), and (A3) in the polyolefin resin satisfies the following formula (1), and wherein the units (A1), (A2), and (A3) are the only repeating structural units in the polyolefin resin: 0.01≦( A 2)/{( A 1)+( A 2)+( A 3)}×100≦30 Formula (1) (A1): a repeating structural unit represented by the following formula (11): where R 11 to R 14 each independently represent a hydrogen atom or an alkyl group; (A2): a repeating structural unit represented by the following formula (22): where R 25 and R 26 each independently represent a hydrogen atom, an alkyl group, or a phenyl group, and X 21 represents a divalent group represented by -Y 22 COOCOY 23 - where Y 22 and Y 23 each independently represent a single bond, an alkylene group, or an arylene group; and (A3): a repeating structural unit represented by any one of the following formulae (31), (32), (33), and (34): where R 31 to R 35 each independently represent a hydrogen atom or a methyl group, R 41 to R 43 each independently represent an alkyl group having 1 to 10 carbon atoms, and R 51 to R 53 each independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms.
