Method of manufacturing toner, apparatus for manufacturing toner, and method of manufacturing resin particle

An apparatus for manufacturing toner, comprising:

• a liquid droplet forming device including:
• a liquid column resonance liquid chamber having a plurality of nozzles;
• and
• a vibration generator adapted to vibrate a toner constituents liquid in the liquid column resonance liquid chamber to form a liquid column resonance pressure standing wave therein so that the toner constituents liquid is discharged from the nozzles;
• and
• a liquid droplet solidifying device adapted to solidify the liquid droplets,
• wherein the toner constituents liquid includes an organic solvent and toner constituents dissolved or dispersed in the organic solvent, the toner constituents including a resin, a colorant, and a release agent,
• wherein the nozzles are disposed within an area including an antinode of the liquid column resonance pressure standing wave, and
• wherein one of the nozzles disposed closer to a node of the liquid column resonance pressure standing wave has a smaller outlet diameter than that disposed farther from the node, and the toner constituents liquid is applied with a uniform pressure at a vicinity of each nozzle.

A method of manufacturing resin particle, comprising:

• forming liquid droplets, including:
• vibrating a liquid in a liquid column resonance liquid chamber having a plurality of nozzles to form a liquid column resonance pressure standing wave therein;
• and
• discharging the liquid from the nozzles;
• and
• solidifying the liquid droplets,
• wherein the liquid is a melted resin or an organic solvent solution or dispersion of a resin,
• wherein the nozzles are disposed within an area including an antinode of the liquid column resonance pressure standing wave, and
• wherein one of the nozzles disposed closer to a node of the liquid column resonance pressure standing wave has a smaller outlet diameter than that disposed farther from the node, and the liquid is applied with a uniform pressure at a vicinity of each nozzle.
