Abstract
A method for the preparation of electrostatographic toner comprising the steps of: PA1 a) dissolving a polymer material in an organic solvent to form an organic phase; PA1 b) dispersing the organic phase in an aqueous phase comprising a salt selected from aluminum salt and gallium salt and a particulate stabilizer to form a dispersion and homogenizing the resultant dispersion; PA1 c) evaporating the organic solvent and recovering a resultant product; and PA1 d) washing and drying the resultant product.
