摘要： Herein is disclosed a process for producing emulsion aggregation toner including (i) adding a base to an emulsion aggregation toner to increase the pH of the toner to from about 7 to about 12; (ii) sieving and filtering the toner; (iii) washing the toner with an enzyme selected from the group consisting of carboxylic ester hydrolase and sulfuric ester hydrolase; (iv) filtering the toner; (v) washing the toner with reverse osmosis or deionized water; and (vi) adding an acid to reduce the pH of the toner to from about 3 to about 8.
