An electrophotographic magnetic carrier of the present invention has an average particle diameter of 10 to 300 mu m and comprising a composite particle having a two-layered structure, comprises: magnetic particle as a core particle; a coating layer formed on the surface of the magnetic particle, comprising surface-treating agent having an amino group; and an outer layer formed on the surface of the surface-treating agent layer, comprising an inorganic material and a cured phenol resin, the ratio (rb/ra) of an average radius (rb) of the core particle to a thickness (ra) of the outer layer being in the range of 10:1 to 300:1. The electrophotographic magnetic carrier not only has a high saturation magnetization and a freely controllable charge amount, but also is free from falling-off or separation of magnetic fine particles from a core particle.
