    摘要: An electrophotographic carrier, which has high charging characteristics and an excellent durability, does not dull a color image and has an excellent moisture resistance is provided. A process for the production of the carrier and a developing agent for electrophotography using the carrier are also provided. The electrophotographic carrier comprises a carrier core material provided with magnetism and a coating layer formed on the surface of the carrier core material, the coating layer containing at least a hydrophobic white conductive material and a high molecular weight polyethylene resin.
