    摘要： Disclosed is a process for preparing a liquid or dry electrophotographic developer comprising: (a) forming a melt mixture comprised of a polymer resin or resins, a colorant, a charge director, and a nonaqueous solvent to obtain a first suspension of colored polymeric particles with a volume average diameter of from about 5 to about 100 microns; and (b) homogenizing with a dairy piston homogenizer said first suspension under pressure of from about 100 to about 500 Bars to obtain a second suspension containing colored polymeric particles with a volume average diameter of from about 0.1 to about 5 microns.
