<p>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: äF(CF2)a1-Q1-R1.m1SiO(3-m1)/2üX1äF(CF2)a2-Q2-R2.m2SiO(3-m2)/2üX2.... äF(CF2)ap-Qp-Rp.mpSiO(3-mp)/2üXpäR1'n1SiO(4-n1)/2üy1- äR2'n2SiO(4-n2)/2üy2....äRq'nqSiO(4-nq)/2üyq where R1, ..., Rp, R1', ..., and Rq' are respectively an alkyl or aryl group; Q1, ..., and Qp are respectively an alkylene group; m1, ..., and mp are respectively an integer of 0 to 2; n1, ..., and nq are respectively an integer of 0 to 3; a1, ..., and aq are respectively an integer; x1 and y1 are respectively a number larger than 0; and x2, ..., and xp, and y2, ..., and yq are respectively a number of 0 or more. <IMAGE></p> |
