Abstract
A method for producing a toner, including ejecting a toner composition liquid containing at least a resin and a colorant periodically from a plurality of nozzles into a chamber using a vibration unit, so as to form droplets in a gas phase; and solidifying the droplets, wherein the droplets are transported by transport air flow selected from at least one of vertical downward air flow and rotational air flow, and the method can prevent toner particles from aggregation.
