    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 &OHgr;·cm and not more than 5.0×1012 &OHgr;·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.

    摘要： An electrophotographic photosensitive member that can not easily cause charging lines even where it is an electrophotographic photosensitive member employing as a conductive layer a layer containing metal oxide particles is disclosed. Also disclosed are a process cartridge and an electrophotographic apparatus which have such an electrophotographic photosensitive member. The electrophotographic photosensitive member has a conductive layer which contains titanium oxide particles coated with tin oxide doped with phosphorus or tungsten.
