Magnetic carrier for electrophotograph-developing agent, process for production thereof, and two-component developing agent |
| abstract |
Disclosed is a magnetic carrier for an electrophotograph-developing agent, which comprises spherical complex particles each comprising: a spherical complex core particle comprising at least a ferromagnetic iron oxide iron microparticle and a cured phenolic resin and having an average particle diameter of 1 to 100 μm; and a coating layer formed on the surface of the spherical complex core particle and comprising a melamine resin. The magnetic carrier is characterized by having a ratio R 100 /R 300 of 1 to 50 wherein R 100 represents an electric resistivity of the magnetic carrier as measured by applying a voltage of 100 V and R 300 represents an electric resistivity of the magnetic carrier as measured by applying a voltage of 300 V. The magnetic carrier can keep the electric resistivity at a proper level during developing, and can be used in an electrophotograph-developing agent that enables the long-term retention of a high-quality image having excellent image quality and durability, capable of achieving the reproducibility of high-density and uniform solid black parts, and having excellent tone properties and the like. |
