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

Patent number: 8383310Abstract: The present disclosure relates to a binder resin system suitable for use in forming toner compositions. In embodiments, the binder resin system includes at least one amorphous resin, at least one crystalline resin, and at least one fatty acid salt. The presence of the fatty acid salt reduces plasticization which may otherwise occur upon combining the amorphous and crystalline resins, thereby increasing the glass transition temperature of the binder resin, as well as any toner produced with such binder resin. Toners produced with the disclosed binder resin may also include one or more optional ingredients such as optional colorants, optional waxes, and combinations thereof.Type: GrantFiled: April 27, 2010Date of Patent: February 26, 2013Assignee: Xerox CorporationInventors: Mark E.
