Abstract

A method of manufacturing toner is provided. The method includes preparing a first liquid by dissolving or dispersing toner components in an organic solvent, preparing a second liquid by emulsifying the first liquid in an aqueous medium, and evaporating the organic solvent from the second liquid. The toner components include a colorant, a release agent, and one or both of a binder resin and a precursor thereof. The evaporating includes flowing down the second liquid as a liquid film in substantially a vertical direction along an inner wall surface of a pipe that is depressurized, heating the liquid film at a temperature not higher than a glass transition temperature of the binder resin, and supplying the pipe with a depressurized water vapor from a supply opening disposed on an upper part of the pipe.
