Disclosed is a method of making particulates. A solution is formed of a solvent. a first polymer having an intrinsic viscosity of at least 0.5, and a second polymer having an intrinsic viscosity of less than 0.5. The solution is atomized with a gas to form droplets of the solution suspended in the gas. The evaporation of the solvent leaves the particles suspended in the gas and the particles are collected to form the toner. Also disclosed is toner made by this method, and a method of making an electrographic printing plate by developing an electrostatic image with the toner, transferring the developed image to a substrate, and fixing the transferred image on the substrate. Also disclosed is an electrographic printing plate made according to that method.
