Disclosed herein is a toner collection apparatus comprising a receptacle 10 herein disclosed as a bottle which is supported in its operative position by a machine frame member 12 so that an opening 14 therein is disposed at the side thereof adjacent a top wall 16 of the receptacle. An auger 18 disposed in an auger housing 19 is provided for moving the residual toner that is delivered to the auger housing from a conduit 20 into the receptacle. The auger 18 is provided with a pulley 22 which is operatively coupled to a machine drive (not shown) for impacting rotary motion thereto. Portion 24 of the auger housing encircles a part of the auger and together with that part of the auger is installed in the bottle such that an outlet or tip 26 thereof extends into the receptacle a distance equal to approximately 1/4 to 1/2 the length of the receptacle. This distance is chosen such as to optimize the backfilling of the bottle. Backfilling is the filling of the receptacle between the tip of the auger from where the toner exits and the opening 14 inlet of the receptacle which is formed integrally with a vertical wall 28 of the receptacle. The portion of the housing encircling the auger forms a channel through which the residual toner is transported. To prevent residual toner from spilling out of the bottle through the opening 14 there is provided a foam seal 30. The end of the auger housing opposite the tip 26 comprises a hopper 32 for receiving residual toner from the conduit 20.
