主权项 1. An electrophotographic photosensitive member comprising: a photosensitive layer, wherein the photosensitive layer is either a single-layer photosensitive layer containing a charge generating material, a hole transport material, and a binder resin, ora multi-layer photosensitive layer in which a charge generating layer containing the charge generating material and a charge transport layer containing the hole transport material and the binder resin are stacked, the hole transport material contains an amine stilbene derivative HTM-5 represented by a chemical formula (11) or an amine stilbene derivative HTM-6 represented by a chemical formula (12), the charge generating material contains PY-128 represented by a chemical formula (28), and the binder resin contains a polycarbonate resin represented by a general formula (2), in the general formula (2), R21 and R22 each represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, or a phenyl group, or R21 and R22 are bonded together to form a cycloalkylidene group having 5 to 8 carbon atoms,R23 to R25 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, andp+q=1 and p≧0.4 are both satisfied.
