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 a conductive layer hardly occurs, and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member. To this end, the conductive layer of the electrophotographic photosensitive member contains a titanium oxide particle coated with tin oxide doped with phosphorus, a tin oxide particle doped with phosphorus, and a binding material, and when a total volume of the conductive layer is represented by V T , a total volume of the titanium oxide particle coated with tin oxide doped with phosphorus in the conductive layer is represented by V 1P , and a total volume of the tin oxide particle doped with phosphorus in the conductive layer is represented by V 2P , the V T , the V 1P , and the V 2P satisfy the following expressions: 2≦{(V 2P /V T )/(V 1P /V T )}×100≦25 and 15≦{(V 1P /V T )+(V 2P /V T )}×100≦45. |
