Provided are an electrophotographic photosensitive member in which a residual potential hardly increases at the time of image formation, a pattern memory hardly occurs, and the crack of an electro-conductive layer hardly occurs, and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member. To this end, the electro-conductive layer of the electrophotographic photosensitive member contains titanium oxide particles coated with tin oxide doped with phosphorus, tin oxide particles doped with phosphorus, and a binding material, and when a total volume of the electro-conductive layer is represented by VT, a volume of the titanium oxide particles coated with tin oxide doped with phosphorus in the electro-conductive layer is represented by V1P, and a volume of the tin oxide particles doped with phosphorus in the electro-conductive layer is represented by V2P, the VT, the V1P, and the V2P satisfy the following expressions: 2<={(V2P/VT)/(V1P/VT)}x100<=25 and 15<={(V1P/VT)+(V2P/VT)}x100<=45. |
