摘要：
A method of preparing a toner, including periodically dripping and discharging droplets of a toner constituent liquid comprising a resin and a colorant with a dripper comprising a thin film comprising plural nozzles configured to discharge the droplets, and an electromechanical converter configured to oscillate the thin film; and solidifying the droplets to form toner particles, wherein the nozzle has an aperture discharging the droplet, having a circular or an ellipsoidal cross-sectional shape and cross-sectional area smaller than a cross-sectional area of another aperture contacting the toner constituent liquid.
