<p>A carrier core particle for an electrophotographic developer includes a composition expressed by a general formula: Mn x Fe 3-x O 4+y (0<x‰¤1, 0<y), a full width at half maximum z of the most intense peak (311) plane in a powder X-ray diffraction pattern satisfying 0.16 (degree) ‰¤ z, and a magnetization of 50 emu/g or higher in an external magnetic field of 1000 Oe.</p> |
