摘要:
A method for producing a toner, including ejecting a toner composition liquid containing at least a resin and a colorant periodically from a plurality of nozzles into a chamber using a vibration unit, so as to form droplets in a gas phase; and solidifying the droplets, wherein the droplets are transported by transport air flow selected from at least one of vertical downward air flow and rotational air flow, and the method can prevent toner particles from aggregation.
摘要:
A toner produced by dissolving or dispersing toner components comprising a binder resin, a colorant, and a charge controlling agent in an organic solvent to prepare a toner components liquid, forming liquid droplets of the toner components liquid in a gas phase, and solidifying the liquid droplets into toner particles of the toner. The charge controlling agent includes a polycondensation reaction product of a phenol with an aldehyde.
摘要:
A method for manufacturing toner includes steps of supplying, periodically dispensing, and solidifying. The supply step supplies a liquid to be atomized, which includes at least a resin and a colorant. The periodic dispensation step periodically dispenses droplets of the liquid through an atomizing unit. The solidification step solidifies the dispensed droplets into toner particles. The atomizing unit includes a thin film, a vibration actuator, and multiple holes. The thin film has a relatively stiff portion and a relatively elastic portion, and is configured to contact the liquid. The vibration actuator is connected to and supports a periphery of the thin film, and is configured to induce vibration of the thin film. The multiple holes are formed in the relatively stiff portion, and are configured to discharge droplets therethrough when the thin film vibrates.
摘要:
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.
