摘要： There are adopted: an electrophotographic developer carrier that includes on the surface of a carrier core material a coating resin including a silicone resin containing a fluorine silane coupling agent, has an intensity ratio (F/Si), measured with fluorescent X-ray, between the fluorine atom and the silicon atom present on the carrier surface of 1.4×10−3 to 2.0×10−3, and has an intensity ratio (F/Fe), measured with fluorescent X-ray, between the fluorine atom and the iron atom present on the carrier surface of 2.3×10−5 to 3.5×10−5; and an electrophotographic developer using the carrier.
