CA 2399572
The present invention relates to a toner and process for making the improved toner. The improved toner comprises a toner resin comprising: at least one colorant; (b) at least one toner resin mixed with the colorant and formed into combined colorant and resin particles having an average size less than 15 microns ; and (c) surface additive particles wherein the surface additives are adhered to the colorant and toner resin by an impaction process in a quantity greater than three (3) percent of the combined weight of resin and colorant in the toner. The invention also relates to an improved process for making toners, comprising: (a) forming toner particles averaging 4 to 10 microns in size and comprised of at least one toner resin and at least one colorant; and (b) blending sufficient surface additive particles and the toner particles in a high intensity blender for less than 10 minutes such that the weight of surface additives that become attached to toner particles is greater than three (3) percent of the weight of the classified particles
