Abstract
Apparatus for removing toner from a charge-retentive surface and collecting the toner in a receptacle for subsequent disposal thereof. This apparatus is characterized by the provision of a segmented auger structure which is disposed internally of the receptacle such that toner is moved into the receptacle through a vertical one end thereof and positively transported by auger action across the entire length of the receptacle. The segmented auger functions to move toner by means of the two auger sections and causes toner moved by the auger sections to push toner between the two auger sections and between one of the auger sections and the end of the receptacle.
