| abstract | (57) [Summary] (Corrected) [Purpose] Even in the development of an alternating electric field, there is no carrier adhesion, excellent spent resistance, resistance value, and stability of imparting charge to toner. [Structure] In a magnetic carrier having a core material surface coated with a resin, the particle size of the carrier is 5 to 100 μm, the bulk density is 3.0 g / cm 3 or less, and the magnetic properties of the carrier are as shown in the figure. And σ 1000 is 30 to 150 em u / cm 3 , σr of 25 emu / cm 3 or more, coercive force of less than 300 Oersted, a carrier satisfying the following formula, and the resin coating the core material surface is It is composed of a vinyl copolymer having a hydroxyl value of 1 to 100 or a styrene-acrylic copolymer, and the monomer ratio of the acrylic component in the copolymer is 30 to 90% by mass, and Weight average molecular weight is 300 It is a copolymer having a weight average molecular weight / number average molecular weight of 2 to 10 and a weight average molecular weight of 0 to 70,000. |
