Abstract
A cross-linked low surface adhesion composition, that can be utilized as either an electrographic toner powder or as an additive for conventional electrographic toner powder, exhibits improved transfer and contributes to an increase in the useful life of the developer. The low surface adhesion composition employs a silicone resin and a polyester resin cross-linked with a polyfunctional epoxy novolac resin.
