Abstract
Official abstract text for this publication.
A removable unit for an electrophotographic image forming device according to one example embodiment includes a housing having an inner volume forming a toner reservoir and a channel for accumulating toner. The removable unit further includes an auger for advancing toner within the channel. The auger has a rotational axis and a flight. An agitator is pivotally mounted within the toner reservoir. The agitator has at least one agitating member extending near the auger and a cam surface operatively connected to the at least one agitating member and positioned to engage the auger. When the auger rotates, the flight of the auger engages the cam surface causing pivotal movement of the agitator to move the at least one agitating member to agitate toner accumulated near the auger.
