| titleOfInvention | Resin-coated carrier, two-component developer and image forming method |
| abstract | A two-component developer suitable for electrophotography is formed of a toner and a resin-coated carrier. The resin-coated carrier is formed of carrier core particles and 0.01-2.0 wt. % based on the carrier core particles of a resin coating layer coating the carrier core particles. The resin-coated carrier has an average particle size of 25-55 μm and the carrier core particles comprise a ferrite component represented by formula (I) below: n n n (Fe 2 O 3 ) a (MnO) b (MgO) c (A) d (I), n n n wherein A represents a mixture of SrO, CaO and Al 2 O 3 , and a, b, c and d are numbers representing mol fractions of associated components and satisfying: 0.4<a<0.6, 0.35<b<0.45, 0.07<c<0.12, 0.005<d<0.015, and a+b+c+d≦1. Because of the specific composition, the carrier core particles are provided with a smooth surface, which is reflected into a surface smoothness of the resin-coated carrier even after coated with a thin resin coating layer. Accordingly, the resin-coated carrier is provided with a good balance among toner-charging ability, flowability and durability suitable for reproduction of an original having a large areal percentage. |
