Abstract
A method of manufacturing toner is provided. In the method, toner constituents are dissolved or dispersed in an organic solvent to prepare a toner constituents liquid. The toner constituents liquid is degassed so that the toner constituents liquid includes dissolved oxygen in an amount of 3 mg/L or less. The toner constituents liquid is vibrated in a chamber having at least one nozzle to form a liquid column resonance standing wave in the toner constituents liquid. The toner constituents liquid is discharged from the nozzle disposed within an area including an antinode of the liquid column resonance standing wave to form the toner constituents liquid into liquid droplets. The liquid droplets are dried to solidify the liquid droplets into solid particles.
