摘要

A carrier for electrostatic image development comprising a resin coated carrier particle which comprises a core particle and a resin coated on the surface thereof, whose resin is coated by a dry method with secondary particles composed of elementary resin particles with a volume average particle size of not more than 0.5 mu m that are fused on their surface, wherein the secondary particles have BET specific surface areas of 5 to 150 m<2>/g; and a volume average particle size of 1.5 to 5.0 mu m.
