MAGNETIC CARRIER, TWO-COMPONENT DEVELOPER, DEVELOPING UNIT, DEVELOPING DEVICE, IMAGE-FORMING APPARATUS, AND IMAGE-FORMING METHOD
摘要
<p>In a magnetic carrier, the surface of a magnetic body core material is coated with a coating layer containing conductive particles and a charge control agent composed of the same components as the charge control agent contained in the toner for electrophotograph. Furthermore, the electric resistance of the magnetic carrier under an electric field of 4 x 103 V/cm is from 8.22 x 107 to 1.12 x 1010 Ocm. The ability of charging the toner for electrophotograph can be sustained even after a long time.</p>
