    摘要: A method for producing an electrophotographic photosensitive member in which leakage hardly occurs is provided. For this, in the method for producing an electrophotographic photosensitive member according to the present invention, a coating liquid for a conductive layer is prepared using a solvent, a binder material, and a metallic oxide particle having a water content of not less than 1.0% by mass and not more than 2.0% by mass; using the coating liquid for a conductive layer, a conductive layer having a volume resistivity of not less than 1.0×108 Ω·cm and not more than 5.0×1012 Ω·cm is formed; the mass ratio (P/B) of the metallic oxide particle (P) to the binder material (B) in the coating liquid for a conductive layer is not less than 1.5/1.0 and not more than 3.5/1.0; and the metallic oxide particle is selected from the group consisting of a titanium oxide particle coated with tin oxide doped with phosphorus, a titanium oxide particle coated with tin oxide doped with tungsten, and a titanium oxide particle coated with tin oxide doped with fluorine.
