Abstract:
1. A method for producing a toner, comprising: periodically forming and discharging liquid droplets of a toner composition liquid containing at least a resin, a releasing agent and a colorant from a plurality of nozzles formed in a thin film which is provided in a reservoir for the toner composition liquid, by vibrating the thin film using a mechanically vibrating unit, and forming toner particles by solidifying the liquid droplets of the toner composition liquid, wherein the forming toner particles comprises primarily drying the liquid droplets discharged from the nozzles of the thin film under a stream of dry gas containing an organic solvent whose partial pressure is equal to or higher than 1/10 of a saturated vapor pressure thereof but is equal to or lower than the saturated vapor pressure, the saturated vapor pressure being that at a drying temperature; and secondarily drying the primarily dried liquid droplets for solidification while the organic solvent is being evaporated.
