摘要：
To provide an electrophotographic photosensitive member that can reproduce good images with less positive ghost and also has a good photosensitivity, the electrophotographic photosensitive member is incorporated in its photosensitive layer with a copolymer having a repeating structural unit represented by the formula (1) and a repeating structural unit represented by the formula (2), or a copolymer having a repeating structural unit represented by the formula (1) and a repeating structural unit represented by the formula (3).
