Abstract:
An electrophotographic photosensitive member comprising, in sequence:(a) an electroconductive support; and(b) a photosensitive layer wherein an outer surface of said photosensitive member contains a binder resin, a silicon denatured polycarbonate copolymer present in amounts from 1 to 30% by weight based on the weight of said binder resin and a silicon-containing graft polymer present in amounts from 0.02 to 10% by weight based on the weight of solids in the outer surface, wherein said silicon denatured polycarbonate copolymer has a structure of the following formula (I): ##STR24## wherein A is a straight chain, branched chain or cyclic alkylidene group, an aryl-substituted alkylene group, a substituted or unsubstituted arylene group, --O--, --S--, --SO--, --SO.sub.2 --, or --CO--, R.sub.1 to R.sub.16 are hydrogen atoms, halogen atoms, substituted or unsubstituted alkyl groups, or substituted or unsubstituted aryl groups, R.sub.17 to R.sub.20 are substituted or unsubstituted alkyl groups or substituted or unsubstituted phenyl groups, l, m and n are integers larger than 1, and the sum of X and Y is 100 wherein X:Y is from 99.5:0.5 to 10:90 and wherein said silicon-containing graft polymer includes, as a component thereof, a polymerizable monomer incorporating a side chain having a silicon atom.
