摘要：
An electrophotographic photosensitive member has a photosensitive layer formed on a support. A surface layer (or the outermost layer) of the photosensitive layer contains a fluorine-modified organic silicone resin represented by the following average unit formula:{F(CF.sub.2).sub.a1 -Q.sub.1 -R.sub.1.m1 SiO.sub.(3-m1)/2 }.sub.X1 {F(CF.sub.2).sub.a2 -Q.sub.2 -R.sub.2.m2 SiO.sub.(3-m2)/2 }.sub.X2 . . . {F(CF.sub.2).sub.ap -Q.sub.p -R.sub.p.mp SiO.sub.(3-mp)/2 }.sub.Xp {R.sub.1 '.sub.n1 SiO.sub.(4-n1)/2)}.sub.y1 {R.sub.2 '.sub.n2 SiO.sub.4-n2)/2 }.sub.y2 . . . {R.sub.q '.sub.nq SiO.sub.(4-nq)/2 }.sub.yqwhere R.sub.1 -R.sub.p and R.sub.1 '-R.sub.q ' are each an alkyl or aryl group; Q.sub.1 -Q.sub.p are each an alkylene group; m1-mp are each an integer of 0 to 2; n1-nq are each an integer of 0 to 3; a1-aq are each an integer; x1-y1 are each a number larger than 0; and X2-Xp and Y2 are each respectively a number of 0 or more.
