摘要： Toner particles are prepared by a process comprising providing an extrusion apparatus; adding resin particles and additive particles to a supply means in the extrusion apparatus; adding the resin particles and the additive particles to a blending chamber in the extrusion apparatus, which blending chamber is maintained at a temperature of from about 50° C. to about 120° C.; blending the resin particles and the additive particles to form a mixture; extruding the resin particles to form extruded material; injecting liquid substances, which have a lower boiling point than the melt temperature of the resin particles, into the blending chamber during extrusion without the application of a vacuum to remove the liquid substances prior to extrusion; and grinding the extruded material to form toner particles.

摘要： 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.
