摘要：
A production method of electrostatic latent image developing toner, comprising: a colored particle forming step of forming colored particles in water-based medium; a first separation step of separating the colored particles from the water-based medium; a dispersing step of dispersing the colored particles into a washing medium; a skimming step of skimming impurities other than the colored particles together with at least a part of the washing medium, the impurities drifting on the washing medium; and a drying step of dry the colored particle so as to make the water content of the colored particles being 3% or less.
