Abstract:
An electrophotographic photosensitive member includes a conductive substrate, a charge generating layer, and a charge transport layer. The charge generating layer has a thickness of at least 0.07 μm. The charge transport layer contains a binder resin, a hole transport material, and meta-terphenyl. The binder resin includes a polyarylate resin including repeating units and a group represented by respective general formulas (1) to (3). The electrophotographic photosensitive member satisfies at least two conditions of: (A) the charge generating layer has a thickness of at least 0.12 μm; (B) the charge transport layer contains a specific amount of fluororesin particles; and (C) the charge transport layer contains meta-terphenyl in an amount of at least 5.0 parts by mass and no greater than 15.0 parts by mass relative to 100 parts by mass of the binder resin.
