SOLUTION: The carrier 1 is a coated carrier having wear resistance and comprising a carrier core material 6 and a coating layer 7 coating the carrier core material 6, in which the surface of the carrier core 6 is partially exposed. When a shape factor (SF-2) of the carrier core material 6 is denoted as a first shape factor, that of the initial carrier 1 is denoted as a second shape factor, and that of the coated carrier changed by wear of the carrier core material 6 and the coating layer 7 of the initial carrier 1 is denoted as a third shape factor, respectively, the first shape factor ranges from 120 to 150, and a ratio of the third shape factor to the second shape factor is not less than 90%. Thereby, as a wear balance in the resin coated portion where a concave portion is formed can be optimized and decrease in the shape factor with time can be prevented, decrease in a conveyance amount of the developer can be suppressed.
