Abstract

An apparatus is disclosed for removing large particles from a toner powder image developed on a latent image which is recorded on an image receiving member. The apparatus includes a nozzle (100), interposed between the development station (C) and the transfer station (D) at which the toner powder image is transferred to a copy sheet. The nozzle directs a high velocity flow of gas across the toner powder image to remove large particles therefrom without affecting image integrity.
