ABSTRACT:
A dry nonelectroscopic toner surface coated with 3 to 40% by weight of an organofunctional substituted fluorocarbon compound. Toners of the invention are useful for developing photosensitive elements having imagewise tacky and complementary nontacky image areas. The surface coating imparts good toning and clean-up characteristics, together with improved performance on aging.
