Abstract
An electrophotographic photosensitive member includes a laminated body, the laminated body including a support, an undercoat layer, and a charge generating layer. The undercoat layer includes a polymerized product of a composition including an electron transport material represented by formula (1), a cross-linking agent, and a thermoplastic resin having a polymerizable functional group, the laminated body satisfying expressions (2) and (3)Z—X—Z  (1)0.20≦|2−1|≦2.0  (2)τ≦10  (3)in which Zand Zare groups having electron transport property, X is a linker, Vd2 and Vd1 are surface potentials of the charge generating layer after charging and τ is transit time based on a change rate of the surface of the charge generating layer, each as defined in the specification.
