A particulate material production method is provided. The particulate material production method includes ejecting a particulate material composition liquid, which includes an organic solvent and a particulate material composition including at least a resin and dissolved or dispersed in the organic solvent, from at least one nozzle to form droplets of the particulate material composition liquid in a gas phase; and solidifying the droplets of the particulate material composition liquid to prepare particles of the particulate material composition. The droplet solidifying step includes contacting the droplets with a poor solvent for the particulate material composition.

A particulate material production apparatus is disclosed. The particulate material production apparatus includes a droplet ejector to eject droplets of a particulate material composition liquid or a melted particulate material composition in a droplet ejection direction from nozzles; a solidifying device to solidify the droplets; a first airflow forming device to form a first airflow to feed the ejected droplets to the solidifying device with the first airflow; and a second airflow forming device to form a second airflow to apply the second airflow the droplets before the droplets are fed by the first airflow. The second airflow forming device forms the second airflow by supplying a pressed gas from a slit, and the traveling direction of the first airflow is substantially perpendicular to the droplet ejection direction.

A method of manufacturing toner is provided. The method includes preparing a toner constituents liquid by dissolving or dispersing toner constituents in an organic solvent. The toner constituents includes a binder resin and a charge controlling agent. The charge controlling agent includes a polycondensation product of a phenol with an aldehyde. The method further includes forming a liquid column resonance standing wave in the toner constituents liquid in a chamber having at least one nozzle by vibrating the toner constituents liquid. The method further includes forming the toner constituents liquid into liquid droplets by discharging the toner constituents liquid from the nozzle. The nozzle is disposed within an area including antinodes of the liquid column resonance standing wave. The method further includes removing the organic solvent from the liquid droplets to solidify the liquid droplets.

The particulate material production method includes vibrating a particulate material composition liquid in a liquid column resonance chamber having at least one nozzle to form a standing wave in the particulate material composition liquid caused by liquid column resonance, so that droplets of the particulate material composition liquid are ejected in a droplet ejection direction from the nozzle so as to fly in a space in a flight direction; feeding a gas in a direction substantially perpendicular to the droplet ejection direction to change the flight direction of the ejected droplets; and solidifying the droplets in the space to produce a particulate material. The particulate material composition liquid includes at least a solvent and a component of the particulate material dissolved or dispersed in the solvent, and the nozzle is located at a location corresponding to an anitnode of the standing wave.

An apparatus for manufacturing fine particles is provided. The apparatus includes a liquid droplet discharge device and a liquid droplet solidification device. The liquid droplet discharge device has multiple nozzles. The liquid droplet discharge device is adapted to discharge a liquid from the multiple nozzles to form the liquid into liquid droplets. The liquid comprises a solvent in which constituents of the fine particles are dissolved or dispersed or a melt of constituents of the fine particles. The liquid droplet solidification device is adapted to solidify the liquid droplets by an airflow. The multiple nozzles are arranged in a manner such that each of the nozzles does not overlap each other relative to a direction of the airflow.
