PROBLEM TO BE SOLVED: To provide a magnetic carrier for an electrophotographic developer used for an electrophotographic developer that has durability, does not generate carrier adhesion, and can maintain high-quality images, and a two-component developer including the magnetic carrier for an electrophotographic developer and a toner.SOLUTION: There is provided a magnetic carrier for an electrophotographic developer that comprises spherical complex core particles comprising at least magnetite particles and a cured phenol resin and having an average particle diameter of 20 to 60 μm, where when the saturation magnetization of carrier particles having a particle diameter approximately the average particle diameter of the magnetic carrier for an electrophotographic developer is σ(Am/kg), the saturation magnetization of carrier particles having a particle diameter smaller than 20 μm is σ(Am/kg), σ-σis within a range of -2 to 0. Also provided is a two-component developer using the magnetic carrier.SELECTED DRAWING: None |
