ABSTRACT:
A developer dispensing apparatus includes a coiled spring used as a slinky auger which is rotated through a developer mixture of toner and carrier beads for dispensing developer through a dispensing opening. The spring auger has a driven end attached to a gear shaft in such a manner that the axis of rotation of the auger is fixed relative to the shaft axis. As the spring auger rotates the tendency of the driven end to ride up on the carrier beads is prevented by the a centering yoke which drivingly connects the drive shaft and the slinky auger. The centering yoke fixes the axis of rotation of the auger so as to inhibit the riding up of the slinky auger on the carrier beads disposed on the bottom of the dispenser.
