X-RAY DETECTABLE ADDITIVES FOR WAX TONER ADDITIVES

Publishing Venue

Xerox Disclosure Journal

Abstract

Toner compositions for use in electrophotographic printers and copiers having x-ray detectable additives for wax toner additives contained therein are disclosed. An x-ray detectable material such as zirconium dioxide, titanium or silicon based materials are blended with wax additives that are used in toner as a lubricant additive. The x-ray detectable particles act as a tag or taggent and serve to identify the presence of and to quantitate the wax component in a toner and thereby allow measurement of the uniformity of wax distribution within the toner mixture. The inclusion of x-ray detectable additives in toners is a useful analytical method for analyzing the amount and the type of toner additives in known toner compositions.
