摘要： 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 μm 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: 3.0≦DV′≦6.0   Relationship 1 4.0≦Dv≦7.5   Relationship 2 1.0≦Dv−Dv′≦3.0   Relationship 3.
