Patent ID: 8252495

Claim:
An electrophotographic toner, comprising toner particles and inorganic fine powder externally added to the toner particles, wherein the toner particles comprise a core particle containing at least a resin, a coloring agent and wax, a first shell layer that is formed on the surface of the core particle to prevent inorganic fine powder from being buried, and a second shell layer that is formed on the surface of the first shell layer to retain inorganic fine powder, wherein the first shell layer is mainly composed of silicon dioxide particles, wherein the second shell layer is mainly composed of resin, wherein the first shell layer is formed by attaching silicon dioxide particles to the surface of the core particle in a dispersion liquid of core particles, then fixing the silicon dioxide particles to the surface of the core particle by heating the dispersion liquid to not less than a glass transition temperature (Tg) of the core particle, and further fixing to one another by adjusting the dispersion liquid to be alkaline.
