Provided is a magnetic carrier satisfying leakage, white spots, charging property and high developing performance in a low electric field and having excellent durability. The magnetic carrier is a magnetic carrier comprising a magnetic substance-dispersed resin carrier core containing a magnetic substance and a binder resin, and a coating resin on a surface thereof, wherein the magnetic substance comprises a magnetic substance A having a shape without vertexes and a magnetic substance B having a shape with vertexes, the magnetic substance B has a number average particle diameter of 0.40-2.00μm, and in a reflection electron image of a section of the magnetic substance-dispersed resin carrier core taken by a scanning electron microscope, an area proportion of the magnetic substance B is larger than an area proportion of the magnetic substance A within a region from the surface of the magnetic substance-dispersed resin carrier core to a depth of 1.0μm. |
