ABSTRACT:
In collecting toner waste from the surface of an image carrier within an image forming apparatus, the toner waste is removed from an image carrier with a cleaning blade. The cleaning blade is at the top of a stack which leads to a storage container. The top of the stack is positioned near the bottom of the image carrier. A sealing member disposed opposite the cleaning blade at the top of the stack conforms to the curved surface of the image carrier and in combination with the cleaning blade and image carrier enclose the top of the stack. Toner waste is thereby prevented from splashing and oozing through the stack during and/or after a copying/printing cycle.
