Patent ID: 7393622

Claim:
A two-component developing agent for electrophotography, comprising: a toner; and a carrier, the carrier containing a core material and a coating layer formed on a surface thereof, and the coating layer being a silicone resin coating layer containing dendritic titanium oxide, wherein an amount of the silicone resin containing titanium oxide to be coated is, based on 100 parts by weight of the core material, 1 to 5 parts by weight, the coating layer contains titanium oxide of 40 to 60 parts by weight on the basis of 100 parts by weight of the silicone resin, said titanium oxide having a shape of 0.04 to 0.07 μm width, 0.2 to 0.3 μm length and has a specific surface area of 70 to 90 m 2 /g; and a surface of the titanium oxide is subjected to a coating treatment by zirconium oxide and aluminum oxide.
