Abstract:
A toner for a two component developer used in a high speed computer output printer has about 20 parts gelled styrene/acrylic resin, 40 parts acrylate resin, about 13 parts hydrogenated wood rosin ester with pentaerythritol, and about 18 parts rosin ester of pentaerythritol, as well as carbon black and a charge control agent. Exceptional improvement is noted in carrier deterioration, fuser roller life and photoconductor filming.
