A process is described to uniformly apply finely divided material to tacky surfaces. The process comprises the physical treatment of particulate material to reduce particle aggregates to smaller particles and depositing the particles on the tacky surface with substantially no shearing force. The particle covered surface is then worked or rubbed with a shearing force to redistribute and embed the particles into the tacky surface. By this process, surfaces which are uniformly tacky or which contain tacky image areas can be uniformly and consistently toned without the production of defects like streaks or mottle.

An apparatus for the application of a controlled quantity of finely divided particulate material on a tacky surface, without imparting any shearing force, having a porous, rotating, laterally movable, cylindrical cartridge for storing and dispensing said particulate material which performs a sieving operation to break up particle aggregates prior to dispensing said particulate material, a roller for transferring said particulate material from the dispensing cartridge to the tacky surface as the roller moves over said surface and, a housing for said elements.
