Zusammenfassung:PROBLEM TO BE SOLVED: To provide a magnetic carrier for an electrophotographic developer having improved durability by increasing adhesiveness between a magnetic carrier core and a coating resin.SOLUTION: The magnetic carrier for an electrophotographic developer comprises spherical magnetic composite particles including magnetic iron oxide particles dispersed in a binder resin. At least magnetic iron oxide particles having an average particle diameter of 0.5 to 30 μm and comprising plurality of granular materials binding one another are used for the magnetic iron oxide particles. A two-component developer using the magnetic carrier is also disclosed.
