Abstract
A development station of electrographic apparatus uses particles of toner to develop latent images on a photoconductor. As the toner particles are depleted a new supply of toner from a container is provided to the development station. Apparatus for adding toner to the development station includes a mounting member having an opening through which toner can pass to the station. A cover hinged to the mounting member moves between closed and open positions, and the cover has an opening that is aligned with the opening in the mounting member when the cover is closed. A shut-off slide in the cover has an opening that can be aligned with the opening in the cover. A container of fresh toner is coupled to the slide and moves with the slide between positions wherein the toner is blocked from flowing through the cover and a position wherein toner from the container can move through the slide, the cover and the mounting member into the development station.
