    摘要: A process for making toner particles is provided. In embodiments, a suitable process includes adding a washing aid agent to toner particles at the time of washing the toner particles prior to their drying and recover. The washing aid agent assist in the removal of ionic species, including surfactants and ions that are part of the emulsion aggregation process, from the resulting toner particles. Utilization of the washing aid agent produces toner particles having improved charging characteristics.

    摘要: A process for making toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin at least one colorant and other optional toner additives, adding to the resin a basic agent and water to form a mixture, and subjecting the mixture to acoustic mixing at a suitable frequency to form to form an emulsion. A phase inversion may then be performed to create a phase inversed emulsion including a disperse phase comprising molten resin and the optional ingredients of the toner composition, at which time toner-sized droplets may be solidified from the disperse phase into toner particles, which can be recovered for use.
