Abstract
A process for preparing electrostatographic toner particles having controlled particle size and size distribution is provided by forming a blend of a molten mass of polymer and a colorant, cooling and solidifying the blend in the form of a film or fiber thereof. The film or fiber is then passed through embossed or cutting rollers to enable fracture of the film or fiber into discrete particles having a size of between 1 micron and about 30 microns.
