ABSTRACT:
A toner material for use in developing images in an electrostatographic device is disclosed. The toner particles are initially classified according to a size distribution wherein less than 15% by weight are greater than 16 microns, between 7 and 15% by weight are less than 5 microns the remainder being from 5 to 16 microns and wherein the median particle size by weight is from 8 to 12 microns. The toner is used in a developer mix with carrier particles, and preferably the toner carrier mix is equilibrated such that the action of the developer mix and the machine provide a toner particle size distribution wherein less than 12% by weight are greater than 16 microns, between 15 and 30% by weight are less than 5 microns, the remainder being from 5 to 16 microns, and wherein the median particle size by weight is between 6.5 and 9.5 microns. An equilibrated toner particle distribution is also disclosed.
