1. 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 the group consisting of 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; and
d) washing and drying the resultant product.
