CARRIER CORE PARTICLE FOR ELECTROPHOTOGRAPHIC DEVELOPER, METHOD FOR MANUFACTURING THE SAME, CARRIER FOR ELECTROPHOTOGRAPHIC DEVELOPER AND ELECTROPHOTOGRAPHIC DEVELOPER |
| 摘要 |
A carrier core particle for an electrophotographic developer includes a composition expressed by a general formula: MnxFe3−xO4+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. |
