A photoconductor coating which is a cross-linked product of a copolymer is disclosed. The copolymer is a polymerization reaction product of reactant monomers comprising three types of monomers. The reactant monomers include from 0.1 to 20 mole percent of one or more first monomers on the reactant monomers, from 0.1 to 20 mole percent of one or more second monomers on the reactant monomers, and from 0.1 to 80 mole percent of one or more third monomers on the reactant monomers. The first monomers has the formula [ STR 1 ] wherein R.sup.1, R.sup.2 each is selected from the group consisting of hydrogen, halogen, alkyl, phenyl, phenylalkyl, and alkylphenyl in which alkyl has 1 to 4 carbon atoms and is linear, R.sup.3 is selected from the group consisting of hydrogen, alkyl, phenyl, phenylalkyl, alkylphenyl, biphenyl, --COOR.sup.5, and --CONHR.sup.6 ; R.sup.5 and R.sup.6 each is selected from the group consisting of hydrogen, fluorine, alkyl, fluoroalkyl, chloroalkyl, alkyl, phenyl, phenylalkyl, and alkylphenyl in which alkyl has 1 to 4 carbon atoms and is linear. The second monomers has the formula [ STR 2 ] wherein R.sup.7, R.sup.8 each is selected from the group consisting of hydrogen, alkyl, phenyl, phenylalkyl, and alkylphenyl in which alkyl has 1 to 4 carbon atoms and is linear, X is a bivalent linking group, and Y is selected from the group consisting of --OH, --NCO, --COR (where R is --H, --OH, alkyl, aryl), --NHR (where R is --H, --OH, alkyl, aryl), anhydride group, and epoxy group. The third monomers are perfluoropolyethers having the formula Z.sup.1 Q.sup.1 (CF.sub.2 CF.sub.2 O).sub.m (CF.sub.2 O).sub.n Q.sup.2 Z.sup.2 wherein m is from about 1 to about 10,000, n is from 1 to 10,000, Q.sup.1, Q.sup.2 each is a polyvalent linking group, Z.sup.1 and Z.sup.2 each has the formula [ STR 3 ] and R.sup.9, R.sup.10 each is selected from the group consisting of hydrogen, alkyl, phenyl, phenylalkyl, and alkylphenyl in which alkyl has 1 to 4 carbon atoms and is linear. The copolymer has a molecular weight of from 1,000 to 500,000.
