Abstract:
1. A magnetic carrier, comprising filled core particles of which pores of porous magnetic core particles are filled with a filling resin composition, and having a surface coated with a coating resin composition, wherein the coating resin composition comprises a coating resin and a carbon black, an amount of the coating resin composition covering the surface of the filled core particles is 2.0 parts by mass or more and 5.0 parts by mass or less with respect to 100.0 parts by mass of the filled core particles; and a particle diameter of the carbon black in the coating resin composition covering the surface of the filled core particles Pv at a maximum frequency in a particle size distribution based on a volume of the carbon black is 1.0 μm or more and 10.0 μm or less, and wherein the coating resin in the coating resin composition has a repeating structural unit derived from a monomer having a cyclic hydrocarbon group.
