ABSTRACT:
A carrier for use in development of an electrostatic latent image and an image forming apparatus using the carrier, with which a stable charging ability is maintained for a long period of time, and a high density image free from fog can be formed. The carrier has magnetic material particles coated with a coating resin. The coating resin is a thermoplastic resin, with a hardness of rank F to B in the terms of the pencil scratch test, and is present in an amount of 0.5 to 5 parts by weight to 100 parts by weight of the magnetic material particles.
