Abstract
A method for the preparation of electrostatographic toner comprising the steps of: a) dissolving a polymer material in an organic solvent to form an organic phase; b) dispersing the organic phase in an aqueous phase comprising a particulate stabilizer to form a dispersion and homogenizing the resultant dispersion wherein a flocculating agent is added to the aqueous phase before or after homogenization; c) evaporating the organic solvent and recovering a resultant product; and d) washing and drying the resultant product.
