Abstract:
1. 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: (A1): a repeating structural unit represented by the following formula (11): where R (A2): a repeating structural unit represented by the following formula (22): where R (A3): a repeating structural unit represented by any one of the following formulae (31), (32), (33), and (34): where R
