Abstract

Disclosed is a method of extending the life of a Viton@ fuser roll used in an electrophotographic printing machine by keeping the fusing roll clean. New additives in color toner have drastically reduced fuser roll life. The cause is believed to be the amine coating on the AerosilB that attaches itself to Viton@ in exactly the same way as amino fuser oil attaches to VitonB. The latter is required for good release. The attached aerosil@, which contains a large number of propylamine groups on the surface, reacts with unsaturated sites in the polyester toner, causing a buildup of toner on the VitonO surface and the subsequent offset failure.
