Patent ID: 10359713

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, and a binder resin. The electron transport material includes a compound having a halogen atom and represented by a general formula (1), (2), (3), (4), or (5). The binder resin includes a polyarylate resin. The polyarylate resin includes at least one type of repeating unit each represented by general formula (11), at least one type of repeating unit each represented by general formula (12), and a terminal group represented by general formula (13). In general formula (13), Rf represents a chain aliphatic group substituted by at least one fluoro group. A charge of calcium carbonate charged by friction between the photosensitive layer and the calcium carbonate is at least +8.0 μC/g.
