ABSTRACT OF THE DISCLOSURE Dry toner particles of an intimate mixture of 25 to 75% by weight of substantially colorless, inert, non- electroscopic spherodial-shape polymer particles of size distribution in the range of greater than 5 to less than 60 µm, nor more than 15% of the polymer particles being less than 10 µm of greater than 50 µm equivalent spherical diameter, and 75 to 25% by weight of colorant particles having a size distribution within the range of 2.2 to 30 µm and not more than 50% of the colorant particles being less than 1 µm particle size. Ionic copolymer spheroidal parti- cles are preferred.
