Patent ID: 10884346

Abstract:
An electrophotographic photosensitive member (1) includes a conductive substrate (2) and a photosensitive layer (3). The photosensitive layer (3) is a single-layer photosensitive layer. The photosensitive layer (3) contains at least a charge generating material, a hole transport material, an electron transport material, and a binder resin. The charge generating material includes a metal-free phthalocyanine. The hole transport material includes a triphenylamine derivative represented by general formula (1) shown below. The electron transport material includes a quinone derivative represented by general formula (2) shown below. In general formula (1), R1, R2, R3, m1, m2, k, p, and q are the same as those described in the description. In general formula (2), R4, R5, and R6 are the same as those described in the description.
