Method of blending toners using a high intensity blending tool with shaped risers for decreased toner agglomeration

Image Number 9 for United States Patent #7235339.

The present invention relates to a method for high intensity blending of toner particles in order to cause additive materials to become firmly affixed to the surface of base toner particles. The method includes using a blending tool having a shank with riser members at each end, such risers being angled outward from the axis of the shank between 10 and 16 degrees and having regions toward the trailing edges that are thicker than regions near the leading edges.
