发明名称 Resin coated carrier for electrophotography and two-component developer for electrophotography made therefrom
摘要 A resin coated carrier for electrophotography and a two-component developer for electrophotography made therefrom, in which electrostatic charge giving ability to toner is high, anti-spent property is superior, charging property is stable even if a large number sheets are continuously printed, initial electrostatic charge increasing ability and electrostatic charge maintaining ability after leaving are also superior, and fogging at supplying toner and fogging after leaving are not generated. In a resin coated carrier for electrophotography comprising a coating material and a core material, in which the coating material covers the surface of the core material, the coating material contains a resin component and a conductive agent, the core material is ferrite, and electric resistance of the carrier at an applied voltage of 100 V set to be 1.0x10<SUP>3 </SUP>to 1.0x10<SUP>6 </SUP>Omega.cm, or breakdown voltage is set to be 120 to 280 V.
