Filed:

Feb 8, 2008

Appl. No.:

12/028053

Inventors:

Timothy L. Lincoln - Rochester NY, US
Timothy J. Key - Rochester NY, US
Robert D. Bayley - Fairport NY, US

Assignee:

Xerox Corporation - Norwalk CT

International Classification:

G03G 9/08

US Classification:

4301081, 4301082

Abstract:

The present disclosure provides polymer-ionic complexes useful as charge control agents. Such charge control agents may be utilized with toner particles to impart excellent triboelectric charging characteristics to the toner.

Abstract:

A toner for particular use in devices utilizing hybrid scavengeless development includes toner particles of at least one binder, at least one colorant, and optionally one or more additives, the toner exhibiting a charge per particle diameter (Q/D) of from -0. 1 to -1. 0 fC/m with a variation during development of from 0 to 0. 25 fC/m and the distribution is substantially unimodal and possesses a peak width of less than 0. 5 fC/m, and the toner has a triboelectric charge of from -25 to -70 C/g with a variation during development of from 0 to 15 C/g following triboelectric contact with carrier particles. Use of a toner with such properties in a hybrid scavengeless development apparatus enables images to be achieved with properties similar to that achieved in offset lithography.
