PURPOSE:To enhance adhesion of a polymer with a carrier core, and durability and electrostatic chargeability by coating the core with the copolymer of a combination of specified monomers of a composition containing said polymer. CONSTITUTION:The carrier core is coated with the copolymer of the 50-99wt.% monomer represented by formula In in which R is H, F, or methyl and Rf is fluoroalkyl, and the 50-1wt.% monomer represented by formula II in which X is H or Cl and Y is Cl, or a composition containing said polymer, thus permitting the coating layer of the carrier made of said copolymer to be superior in film strength and adhesion to the core material, and consequently, to be excellent in durability and to give high chargeability to the carrier. |
