Abstract
A method of preparing a toner, including periodically dripping and discharging a droplet of a toner constituent liquid including a resin and a colorant; and solidifying and granulating the droplet, wherein the dripper includes a thin film including plural nozzles; and an oscillator including an oscillation generator generating an oscillation; and an oscillation amplifier, including an oscillation surface facing the thin film in parallel therewith, amplifying the oscillation, and wherein the toner constituent liquid is fed between the thin film and the oscillation surface.
