Abstract:
An electrophotographic photosensitive member includes a conductive substrate and a photosensitive layer of a single layer. The photosensitive layer contains a charge generating material, a hole transport material, an electron transport material, and a binder resin. An optical response time is at least 0.05 milliseconds and no greater than 0.85 milliseconds. The binder resin includes a polycarbonate resin including a repeating unit represented by general formula (1) shown below and a repeating unit represented by general formula (2) shown below.

Claim (Index 12):
The electrophotographic photosensitive member according to  claim 1 , wherein\n the electron transport material includes at least one of compounds represented by general formulas (21), (22), and (23) shown below, where in the general formula (21), R 1  and R 12  each represent, independently of each other, an alkyl group having a carbon number of at least 1 and no greater than 6, an alkoxy group having a carbon number of at least 1 and no greater than 6, an aryl group having a carbon number of at least 6 and no greater than 14, or an aralkyl group having a carbon number of at least 7 and no greater than 20, in the general formula (22), R 21 , R 22 , and R 23  each represent, independently of one another, a halogen atom, an alkyl group having a carbon number of at least 1 and no greater than 6, an alkoxy group having a carbon number of at least 1 and no greater than 6, an aryl group having a carbon number of at least 6 and no greater than 14 and optionally substituted by a halogen atom, an aralkyl group having a carbon number of at least 7 and no greater than 20, or a heterocyclic group having at least 5 members and no greater than 14 members, and in the general formula (23), R 31  and R 32  each represent, independently of each other, a halogen atom, an amino group, an alkyl group having a carbon number of at least 1 and no greater than 6, an alkoxy group having a carbon number of at least 1 and no greater than 6, or an aryl group having a carbon number of at least 6 and no greater than 14 and optionally substituted by a substituent.
