Patent ID: 8257898

Claim:
A method of manufacturing a toner, wherein a liquid drop forming part comprising a storage part configured to store a toner composition liquid in which a toner composition comprising at least a resin and a coloring agent is dispersed or dissolved, a thin film on which a nozzle facing the storage part is formed, and a vibration generating part configured to vibrate the thin film via the toner composition liquid in the storage part are used to conduct a periodic liquid drop forming process configured to form and eject a liquid drop of the toner composition liquid from the plural nozzles periodically and a particle forming process configured to solidify the ejected liquid drop of the toner composition liquid, wherein plural storage chambers partitioned by a partition wall(s) are formed in the storage part and a width of each storage chamber in a direction of arrangement of the plural storage chambers and a width of each storage chamber in a direction orthogonal to the direction of arrangement of the storage chambers are formed to be one-half or less of a wavelength λ of a sonic wave generated in the storage part.
