    Abstract: An electrophotographic development carrier comprises core particles coated with a fluoropolymer or a mixture of a fluoropolymer and a modifying material. When utilized with appropriate electroscopic toner materials, the carrier, which is coated with the mixture of the fluoropolymer and the modifying material, is effective in producing a desired polarity and magnitude of the triboelectric charge on the toner particles, and the carrier, which is coated with the fluoropolymer, is effective, in producing a triboelectric charge of a desired magnitude on the toner particles. Control of the polarity and magnitude of the triboelectric charge characteristic of the carrier, which has its particles coated with the mixture of the fluoropolymer and the modifying material, is obtained by heating the coated particles to a selected temperature depending upon the desired polarity and magnitude and the particular toner with which the carrier is used. Control of the magnitude of the triboelectric charge characteristic of the carrier, which is coated with the fluoropolymer, is obtained by controlling the curing conditions.

    Abstract: COATED CARRIER PARTICLES WITH MAGNITUDE OF TRIBOELECTRIC CHARGE CONTROLLED AND METHOD OF MAKING SAME An electrophotographic development carrier comprising core particles coated with a carboxylated polyethylene ionomer. When utilized with appropriate electroscopic toner materials, the carrier, which is coated with a carboxylated polyethylene ionomer is effective in producing a desired polarity and magnitude of the triboelectric charge. on the toner particles. Control of the polarity and magnitude of the triboelectric charge characteristic of the carrier, which has its particles coated with the carboxylated polyethylene ionomer is obtained by controlling the curing temperature of the carboxylated polyethylene ionomer.
