摘要:
A toner including a binder resin, a coloring agent, a releasing agent and a modified laminar inorganic mineral, wherein the toner is granulated by dispersing the coloring agent, the releasing agent, the modified laminar inorganic mineral and at least one of the binder resin and a precursor thereof in an organic solvent to form an oil phase, dispersing the oil phase in an aqueous medium to obtain a dispersion emulsion and removing solvents therefrom, and the toner satisfies the following relationship (1): 0.2≦{1/Dv (μm)}×Sb (m2/g)≦1.4, where Dv represents a volume average particle diameter of the toner, and Sb represents a BET specific surface area of the toner.
