Abstract
A method for manufacturing a toner, including periodically forming liquid droplets of a toner constituent liquid comprising a resin and a colorant by vibrating a thin film having a plurality of holes provided on a retention part thereof to discharge the liquid droplets of the toner constituent liquid from the plurality of holes and forming toner particles by solidifying the liquid droplets discharged from the plurality of holes. In periodically forming the liquid droplets of the toner constituent liquid, a flow of gas in a direction of discharge of the liquid droplets is formed by a gas flow generation unit provided downstream from the thin film relative to the direction of discharge of the liquid droplets, including a tapered part forming an aperture corresponding to a hole formation area of the thin film.
