Provided are an electrophotographic photosensitive member which can continuously exert a relieving effect of contact stress with a contact member and the like, and also has excellent potential stability in repeated use, and a process cartridge and an electrophotographic apparatus having the electrophotographic photosensitive member. The charge transport layer, which is the surface layer of the electrophotographic photosensitive member, contains, as a binder resin, a polyester resin having a repeating structural unit represented by the following formula (1) and a repeating structural unit represented by the following formula (2), wherein the content of the siloxane moiety in the polyester resin is poly It is 5 mass% or more and 30 mass% or less with respect to the total mass of ester resin, and content of the polyester resin in a charge transport layer is 60 mass% or more with respect to the total mass of all the binder resins in a charge transport layer. <Formula 1> <Formula 2> |
