A toner producing process comprises the steps of: mixing a solvent, a first binding resin soluble therein, and particles of a coloring agent insoluble therein, with each other, dispersing the particles of the coloring agent in the binding resin while applying a shearing force thereto to obtain a dispersed substance, removing the solvent from the dispersed substance to obtain a coloring agent-binding resin composition in which the particles of the coloring agent are dispersed, mixing the coloring agent-binding resin composition with a second binding resin and a charge controlling agent, melt-kneading the mixture to obtain a kneaded substance and forming toner from the kneaded substance.
