<p>PROBLEM TO BE SOLVED: To provide a carrier for electrophotography, capable of always stably providing a high-quality and high-definition full color copied image. SOLUTION: In the carrier for electrophotography used in developer consisting of at least a toner and a carrier, (1) the carrier used on the developer is magnetic substance dispersion type resin particulates constituted by dispersing magnetic substance powder, (2) the carrier is coated with resin whose specific resistance is >=1013Ωcm under an environment of 23 deg.C and 50% RH, (3) a charge control agent is incorporated in a coating resin layer, (4) the average particle size of the carrier is <=100μm, (5) the specific resistance of the carrier is >=1012Ωcm and further (6) the carrier particles constituted, so that the resin coating rate of the surface of carrier core material is >=90 occupy >=80 number % of the whole.</p> |
