Abstract:
A coated carrier for development of an electrostatically charged image, said coated carrier comprising carrier core particles coated with a coating resin; whereinsaid coating resin at least includes a polyolefin resin having a cyclic structure;a polyolefin resin of a cyclic structure having an intrinsic viscosity (i.v.) of 0.25 dl/g or more, a heat distortion temperature (HDT) by DIN53461-B of 70.degree. C. or higher, and a number average molecular weight of 7,500 or more and a weight average molecular weight of 15,000 or more, as measured by GPC, is contained in an amount of less than 50% by weight based on the entire coating resin; andsaid coating resin is used for coating in an amount of 1 to 30% by weight based on the carrier core particles.
