Patent ID: 8445172

Claim:
A method for producing a toner, comprising: ultrasonically vibrating a liquid toner composition at a vibration frequency of from 10 kHz to 200 kHz in which a toner material containing at least a binder resin and a colorant is dissolved or dispersed in a solvent; introducing the ultrasonically vibrated liquid toner composition to a liquid chamber, and ejecting the liquid toner composition as droplets from an ejecting plate having a plurality of holes and disposed on one surface of the liquid chamber and connected to an ejecting plate vibrating unit; and drying and solidifying the droplets so as to produce a toner, wherein the ultrasonically vibrating is performed before the introducing the liquid toner composition to the liquid chamber, and wherein during the ejecting the ejecting plate vibrating unit vibrates the ejecting plate at a frequency or waveform that is the same as the ultrasonic vibrating of the liquid toner composition.
