Abstract: An electrophotographic photosensitive member includes, in the following order, a support member, an undercoat layer adjacent to the support member, and a photosensitive layer adjacent to the undercoat layer. The undercoat layer contains a polymer produced by polymerizing a composition containing a crosslinking agent and a compound expressed by general formula (1).
