Toner particles of controlled morphology

摘要

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 salt selected from aluminum salt and gallium salt and a particulate stabilizer to form a dispersion and homogenizing the resultant dispersion;c) evaporating the organic solvent and recovering a resultant product; andd) washing and drying the resultant product.
