Patent ID: 8748072

Claim:
A method for producing a toner, comprising: 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 a transport air flow which is a rotational air flow, the transport air flow is obtained by flowing a gas in a shroud arranged covering the nozzles, the shroud has an opening positioned under and facing the nozzles, the shroud including an inner wall and an outer wall connected together with a lid, the inner wall extending near a lower end of a container of the toner composition liquid and the outer wall having an inwardly round shape and extending to a position under the nozzles such that a bottom of the outer wall presents the opening facing the nozzles, the rotational air flow is obtained by generating air flow in a tangential direction with respect to the inner wall of the shroud, and a diameter of the opening is greater than a clearance between an inner surface of the bottom of the outer wall and a lower end of the nozzles.
