Patent number: 8685607Abstract: The continuous process for manufacturing toners disclosed herein includes continuously feeding components of a toner composition into a feed section of a screw extruder at a controlled rate. The continuous process for manufacturing toners may include feeding the components of a toner composition into the feed section of a screw extruder without performing an external or secondary dispersion step. That is to say, the components of the toner composition may be fed directly into the extruder without using dispersions of individual components as used in batch processes. Rather, the toner components are added to the extruder in dry form, melt-mixed, and may be dispersed in aqueous form in the extruder. The process may produce micron-sized toner particles, thus no further size reduction may be necessary.Type: GrantFiled: August 29, 2012Date of Patent: April 1, 2014Assignee: Xerox CorporationInventors: Joo T. Chung, Chieh-Min Cheng, Zhen Lai, Mark E. Mang, Eugene F. Young, Brian Andaya, Joseph Leonardo
