摘要：
A carrier contains a core material; and a coated film containing a binder resin, and a particulate material, the coated film covering the core material, wherein a ratio (D/h) of an average particle diameter (D) of the particulate material to an average thickness (h) of the coated film is from 0.01 to 1, and wherein the carrier has concavities and convexities on the surface of the carrier, the concavities and convexities having a difference of elevation of from 0.05 to 2.0 μm.
