  • Toner process comprising reduced coalescence temperature
    Patent number: 9122179
    Abstract: A method of forming toner particles includes aggregating a mixture of a latex, a wax, and an optional pigment to form pre-toner particles, and coalescing the pre-toner particles at a substantially constant target temperature selected within a range from about the glass transition temperature of the pre-toner particles to about 75° C., thereby creating toner particles having a substantially constant particle size distribution during the coalescing step.
    Type: Grant
    Filed: August 21, 2013
    Date of Patent: September 1, 2015
    Assignee: XEROX CORPORATION
    Inventors: Jay Lee Schneider, Abdisamed Sheik-Qasim, Randy Pheav Tin, Christopher Michael Wolfe, Richard Philip Nelson Veregin, Mark Elliott, Melanie Davis, Cuong Vong, Shigang Steven Qiu

  • Toner process
    Patent number: 8691488
    Abstract: The present disclosure describes a toner produced using a coalescing temperature lower than the melting point of a wax in the toner, quench cooling or both. The resulting toners can exhibit reduced dielectric loss and improved tribo charging.
