Abstract
An electrophotographic photosensitive member includes a conductive substrate, an intermediate layer provided on the conductive substrate, and a photosensitive layer provided on the intermediate layer. The intermediate layer contains a specific polyamide resin and specific inorganic particles. The specific inorganic particles include metal oxide particles. The specific polyamide resin includes a first repeating unit derived from an aliphatic dicarboxylic acid and a second repeating unit derived from a diamine compound. The total percentage content of the first repeating unit and the second repeating unit is at least 80% by mol to all repeating units included in the specific polyamide resin. The photosensitive layer contains a charge generating material, an electron transport material, a binder resin, a hole transport material, and an n-type pigment.
