Abstract:
An electrophotographic photosensitive member includes a conductive substrate and a photosensitive layer having a single-layer structure. The photosensitive layer contains a charge generating material, an electron transport material, a polycarbonate resin, and a hole transport material. The electron transport material includes a compound having a halogen atom and represented by general formula (1), (2), (3), (4), or (5). The polycarbonate resin has a terminal group having a fluoro group and represented by general formula (10). The hole transport material includes a compound represented by general formula (20), (21), (22), (23), (24), (25), (26), or (27). A charge of calcium carbonate as measured by charging the calcium carbonate through friction with the photosensitive layer is at least +6.5 μC/g. The photosensitive layer has a Vickers hardness of at least 17.0 HV at 45° C.

Claim (Index 4):
The electrophotographic photosensitive member according to  claim 1 , wherein\n in the general formula (1), R 1  represents an alkyl group having a carbon number of at least 1 and no greater than 8 and at least 1 halogen atom, in the general formula (2), R 21  and R 22  each represent, independently of each other, an alkyl group having a carbon number of at least 1 and no greater than 4, and R 23  represents a halogen atom, in the general formula (3), R 31 , R 32 , R 33 , R 34 , R 35 , and R 36  each represent, independently of one another: an aryl group having a carbon number of at least 6 and no greater than 14 and at least 1 halogen atom; or an alkyl group having a carbon number of at least 1 and no greater than 6, with the proviso that at least one of R 31 , R 32 , R 33 , R 34 , R 35 , and R 36  represents an aryl group having a carbon number of at least 6 and no greater than 14 and at least 1 halogen atom, X represents an oxygen atom, and Y represents an oxygen atom, in the general formula (4), R 41  and R 42  each represent, independently of each other: an alkyl group having a carbon number of at least 1 and no greater than 8 and at least 1 halogen atom; or an aralkyl group having a carbon number of at least 7 and no greater than 20 and at least 1 halogen atom, and b and b2 each represent 0, and in the general formula (5), R 51  and R 52  each represent, independently of each other: an aryl group having a carbon number of at least 6 and no greater than 14 and at least 1 alkyl group having a carbon number of at least 1 and no greater than 6, and optionally having at least 1 halogen atom; or an aralkyl group having a carbon number of at least 7 and no greater than 20 and optionally having at least 1 halogen atom, with the proviso that at least one of R 51  and R 52  represents a chemical group having at least 1 halogen atom.
