Abstract
Processes for preparing toner compositions used with electrostatographic imaging members. The processes utilize screw extruders to facilitate continuous dispersion and aggregation of toner components, such as color pigments and wax. The continuous dispersion produces the toner components with more control and better product yield. The products produced are also improved in quality.
