In general formulae (1), (2), and (3), R1, R2, R3, R4, R11, R12, R13, R14, R21, R22, R23, and R24 each represent, independently of one another, a hydrogen atom, a cyano group, a halogen atom, an optionally substituted alkyl group having a carbon number of 1-6, or an optionally substituted alkoxy group having a carbon number of 1-6. R5, R6, R15, R16, R25, and R26 each represent, independently of one another, an optionally substituted alkyl group having a carbon number of 1-6, an optionally substituted alkoxy group having a carbon number of 1-6, an optionally substituted aryl group having a carbon number of 6-14, an optionally substituted aralkyl group having a carbon number of 7-12, or an optionally substituted cycloalkyl group having a carbon number of 3-10.

    Abstract: An electrophotographic photosensitive member includes a photosensitive layer containing a charge generating material, a charge transport material, and a binder resin. The photosensitive layer is a multi-layer type photosensitive layer or a single-layer type photosensitive layer. The multi-layer type photosensitive layer includes a charge generating layer that contains the charge generating material and a charge transport layer that contains the charge transport material and the binder resin, and in which the charge transport layer is located on the charge generating layer. The single-layer type photosensitive layer contains the charge generating material, the charge transport material, and the binder resin. The charge transport material is an enamine derivative represented by general formula (1). In general formula (1), R1, R2, l, m, and n are each as defined in the specification.
