发明名称 ELECTROPHOTOGRAPHIC RESIN COATED CARRIER AND ELECTROPHOTOGRAPHIC TWO-COMPONENT DEVELOPER USING THE SAME
摘要 PROBLEM TO BE SOLVED: To provide an excellent electrophotographic resin coated carrier having high ability to impart charges to toner, excellent in spent resistance, ensuring stable charging property even in continuous printing of a large number of sheets, excellent also in initial charge buildup performance and in charge retentivity after being allowed to stand, and causing neither fogging in replenishment nor fogging after being allowed to stand, and to provide an electrophotographic two-component developer using the carrier. SOLUTION: The electrophotographic resin coated carrier is obtained by coating a surface of a ferrite as a core material with a coating agent containing a silicone component and an acrylic component, and an electric resistance of the carrier at an applied voltage of 100 V is 1.0×10<SP>3</SP>-1.0×10<SP>6</SP>Ωcm or a destructive voltage is 120-280 V. The electrophotographic two-component developer comprises electrophotographic toner prepared by sticking a magnetic powder to surfaces of toner particles and the electrophotographic resin coated carrier.
