Abstract
In storing toner waste collected from the surface of an image carrier within an image forming apparatus, the toner waste is compressed within a container by a resilient cantilever member. A diaphragm located within the container expands through an opening of the container based on the pressure exerted on the diaphragm by the compressed toner waste. Upon traveling a predetermined distance, the diaphragm forces a switch to close which triggers an alarm indicating that the container is full of toner waste.
