摘要： A latent electrostatic image developing toner of the present invention is mainly composed of two or more binder resins, a colorant, a releasing agent and a layered compound. A first binder resin of the binder resins is a polyester resin with an acid value of 15 KOHmg/g or less. The layered compound is a compound in which at least some interlayer ions are modified by organic ions. Toner particles are prepared by granulation in an aqueous medium, and the layered compounds are localized in the surface of the particles by the pelletization in the granulation. The average circularity of the particles is 0.970 or more.

摘要： A toner is prepared by wet granulation methods, including a monoester wax having carbon atoms of from 36 to 46 on average as a release agent. The toner has a DSC endothermic energy amount (ΔH1) originating from the wax of from 10 to 12 mJ/mg and a DSC endothermic energy amount (ΔH2) originating from the wax of from 0.6 to 0.9 times as much as ΔH1 after a part of the wax is separated by hexane extraction from the toner. The hexane extraction includes mixing 1 g of the toner in 7 ml of n-hexane to prepare a mixture; stirring the mixture at 120 rpm for 1 min by a pot mill to prepare a dispersion; and subjecting the dispersion to suction filtration.
