Abstract: A process for making an electrophotographic toner comprising: (a) uniformly mixing a metal oxide selected from titanium dioxide and silicon dioxide with toner particles to form a mixture having 5 to 15 weight percent metal oxide; (b) mixing the product of step (a) with additional toner particles at a mixing intensity ≧500,000 (cm/minute) minute; wherein in the mixed product of (b) the metal oxide is 0.1 to 5.0 weight percent of the mixed product; and the toner particles have on their surfaces a metal oxide concentration in a ratio of 1.0-3.0:1.0 with respect to titanium dioxide on the surface of the toner particles:total titanium dioxide in the mixed product; and a ratio of 10.0-25.0:1.0 with respect to silicon dioxide on the surface of the toner particles:total silicon dioxide in the mixed product.
