Patent ID: 7553598

Claim:
A carrier, comprising: 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, wherein the second particulate material has a volume resistivity of not greater than 1.0 ×10 12 Ω·cm, wherein the binder resin is a reaction product of an acrylic resin with amino resin, and wherein said amino resin is guanamine or melamine.
