    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 washing process using one or more ionic liquids (ILs) as a washing aid agent for toners, including toners produced using such ILs, such as, low melt toners, is provided. ILs are environmentally sound, green solvents that act to swell toner particle surfaces so that surface absorbed and adsorbed pollutants, such as, surfactants and other manufacturing reactants, can be effectively removed. The resulting toners have good charging, charge maintenance and RH sensitivity.
