PROBLEM TO BE SOLVED: To use a crosslinked surface layer having high hardness and toughness, very high wear resistance, and little fluctuation in electric characteristics, thereby having excellent durability as well as high stable electric characteristics and high quality images. Provided is an electrophotographic photosensitive member that can be formed over a long period of time. In an electrophotographic photosensitive member having at least a photosensitive layer on a conductive support, a monofunctional radical polymerization in which the surface layer of the photosensitive layer has at least a urethane oligomer having a radical polymerizable functional group and a charge transporting structure. An electrophotographic photosensitive member, which is a crosslinked surface layer formed by curing a functional compound, and the elastic power of the surface layer is 41% or more.
