Abstract
Electrostatographic developer mixtures comprising finely-divided toner particles electrostatically clinging to the surface of carrier particles comprising a core having an outer coating thereon comprising an inorganic metal fluoride. The carrier particles have negative triboelectric charging properties and are particularly useful in reversal development systems. Imaging processes are also disclosed.
