ABSTRACT:
A carrier contains a core; and a cover layer located overlying the core, wherein the cover layer comprises a binder resin, a first particulate material and a second particulate material, wherein the following relationships are satisfied: 1<(D1/h)<10, and 0.001<(D2/h)<1, wherein D1(μm) represents a volume average particle diameter of the first particulate material, D2(μm) represents a volume average particle diameter of the second particulate material, and h (μm) represents a thickness of the cover layer, and wherein the second particulate material has a volume resistivity of not greater than 1.0×1012Ω·cm.
