Abstract: Apparatus is described for applying particulate material to an image-wise tacky surface. The particulate material or toner is dispensed from a hopper having a side wall vibrating laterally of the direction of movement of the surface. The tacky surface is then moved under an applicator which has a brush pad oscillating laterally of the direction of movement of the surface to embed the particulate material in the surface. Finally, the tacky surface is passed under a cleaner which has an agitating surface oscillating laterally of the direction of movement of the surface. A perforated plate is placed under both the cleaner and the applicator to aid in removing excess toner therefrom following use.
