Abstract
An apparatus and method for dispensing toner in an electrostatographic printer includes apparatus for agitating toner contained by a relatively large toner container (e.g., 10-25 liters in volume). The apparatus includes a substantially vertically-oriented shaft supporting a blade that operates, as the blade rotates, to drive the contained toner mass upwardly, thereby aerating the mass and preventing compaction during toner dispensing.
