Abstract
An electrophotographic photoconductor composed of an electroconductive substrate, and a photoconductive layer consisting of a charge generation layer and a charge transport layer successively formed on the substrate in this order, the charge transport layer containing a carbon-carbon double-bond-containing charge transporting material, and a carbon-carbon double-bond-containing monomer or polymer, which serves as a binder resin, and readily reacts with the above-mentioned charge transporting material by the application of light or heat thereto.
Claims9
An electrophotographic photoconductor, comprising an electroconductive substrate, and a photoconductive layer, which comprises a charge generation layer and a charge transport layer successively formed on said substrate in this order, said charge transport layer comprising a reaction product of i) a carbon-carbon double-bond-containing charge transporting material and ii) a binder resin which comprises a carbon-carbon double-bond-containing polymer, said component i) and ii) reacting with each other by the application of light or heat thereto,
- and wherein said carbon-carbon double-bond-containing polymer of said binder resin is selected from the group consisting of an unsaturated polyester obtained from a condensation reaction between maleic anhydride or fumaric acid and a polyhydric alcohol;
- a polyester of phthalic anhydride and glycidyl acrylate obtained by ring opening polymerization;
- a polyester made from acrylic acid, phthalic anhydride and propylene oxide;
- a polystyrene polymer of the formula:
- ##STR17## wherein R.sup.1 represents hydrogen or methyl group;
- and X represents --O--or --CH.sub.2 O--;
- and an acrylic-allyl ester copolymer of the formula:
- ##STR18## wherein R.sup.1 represents hydrogen or methyl group;
- and Y represents a phenyl group or --COO(CH.sub.2).sub.n H, in which n is an integer of 1-10.
