    摘要: An improved carrier particle for use with a toner in electrostatic copying is described. The particle comprises an electroconductive core and a coating. In one embodiment the coating is made by combining a fluorocarbon resin with a charge control agent that has the same polarity as the toner. The carrier imparts a strongly positive triboelectric charge to the toner while resisting adhesion of toner particles.
