Abstract
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.
