A method of manufacturing toner including adding an oil phase comprising an organic solvent in which a binder resin, a coloring agent and a releasing agent are dissolved or dispersed and an aqueous phase to an emulsification device equipped with a stirrer, continuously dispersing or emulsifying the oil phase and the aqueous phase in the emulsification device equipped with a stirrer to form a liquid dispersion or emulsion comprising oil phase particles, transporting the liquid dispersion or emulsion to a tank, removing the organic solvent from the liquid dispersion or emulsion followed by drying to form mother toner particles, wherein the releasing agent has been preliminarily prepared to have a dispersion diameter of from 0.15 to 0.7 mum before the releasing agent is contained in the oil phase, a circumferential speed of the stirrer is from 15 to 25 m/s, and a volume particle diameter (DV') of the oil phase particles at an exit of the emulsification device to the tank and a volume average particle diameter (Dv) of the oil phase particles in the tank satisfy the following relationships: <?in-line-formulae description="In-line Formulae" end="lead"?>3.0<=DV'<=6.0 Relationship 1<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>4.0<=Dv<=7.5 Relationship 2<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>1.0<=Dv-Dv'<=3.0 Relationship 3.<?in-line-formulae description="In-line Formulae" end="tail"?>
