CARRIER FOR ELECTROSTATIC LATENT IMAGE DEVELOPER

PURPOSE:To provide a desired polarity and substantial electrostatic charge quantity to a toner for a long period of time while preventing the generation of spent by coating a resin contg. a specific fluorine-cong. copolymer on a magnetic material. CONSTITUTION:The magnetic material is coated with the resin including the fluorine-contg. copolymer contg. fluoroolefin and alkyl vinyl ether or cycloalkyl vinyl ether as copolymn. components. Such fluorine-contg. copolymer is soluble in an org. solvent such as, for example, toluene and therefore, the above- mentioend resin film is formed on the surface of the magnetic material by a dipping method, etc. using the soln. contg. about 3-20wt% resin by the weight of the org. solvent. The above-mentioned fluoroplastic may be used 100% in this case and, for example, a styrene/acrylate copolymer may be used by blending the same at about
