Image Number 5 for United States Patent #6771922.

A toner cartridge for use in a laser printer has a toner reservoir or hopper in which an agitator is pivoted by a rotating paddle away from its home position proximate an exit opening and then returned to its home position by a spring exerting a predetermined desired force on the agitator after the agitator ceases to be moved by the paddle. The spring may be a cantilever spring, a torsion spring, or a stamped and formed leaf spring.
