    • PROBLEM TO BE SOLVED: To provide a resin composition excellent in abrasion resistance when using as a binder resin of an OPC photoconductor and an electrophotographic photoconductor using the same.
      SOLUTION: A polycarbonate resin is blended with a polysiloxane group-containing A-B type block copolymer consisting of a polysiloxane group-containing copolymer segment-A formed by a vinyl monomer represented by general formula (1) and a polysiloxane group-containing monomer and a polymer segment-B formed by a vinyl monomer represented by the general formula (1), wherein the content of the polysiloxane group-containing monomer is 10 to 85% by weight based upon the polysiloxane group-containing A-B type block copolymer, and the content of the polysiloxane group-containing A-B type block copolymer is 0.03 to 3 pts.wt. based on 100 pts.wt. of the polycarbonate resin, and this composition is used as a binder resin for a photosensitive layer (carrier transport layer), so as to form an electrophotographic photoconductor. In the formula (1), R
      1 represents hydrogen or a methyl group, and R
      2 represents hydrogen, an alkyl group having 1 to 18 carbon atoms, or a hydroxyalkyl group having 2 or 3 carbon atoms.
