Abstract:
A photosensitive member (1) includes a conductive substrate (2) and a photosensitive layer (3). The photosensitive layer is a single-layer photosensitive layer (3c). The photosensitive layer contains a charge generating material, a hole transport material, an electron transport material, and a binder resin. The hole transport material includes a triphenylamine derivative represented by general formula (HT). The electron transport material includes a compound represented by general formula (ET1), (ET2), (ET3), (ET4), or (ET5). The binder resin includes a polyarylate resin represented by general formula (1)
