Abstract:
A carrier for developing an electrostatic latent image, which carrier comprises core particles having formed thereon a resin coating layer, in which the resin coating layer comprises a fluorine-containing resin and a second resin having a softening point lower than that of the fluorine-containing resin, and the resin and the second resin each are partially exposed on the surface of said resin coating layer. The carrier may be produced by a process comprising the steps of: dry-blending core particles, a fluorine-containing resin, and a second resin having a softening point lower than that of said fluorine-containing resin; and melting the resin blend to coat said core particles. The carrier is excellent in stability with time and environmental changes, causes no adhesion, and is less consumed.
