Abstract:
A toner produced by a method including dissolving or dispersing toner components comprising a resin, a colorant, and a release agent in a solvent to prepare a toner components liquid, discharging the toner components liquid from multiple nozzles provided on a thin film by vibrating the thin film by a mechanical vibration unit to form liquid droplets, and drying the liquid droplets into solid particles of the toner. The particle diameter distribution that is a ratio of a weight average particle diameter to a number average particle diameter of the toner is between 1.00 and 1.15, and a weight average particle diameter of the release agent in the toner is between 1% and 30% of an aperture diameter of the nozzle.
