Abstract:
A system and method for urging stray toner away from sealing areas on rotating shafts in electrostatic process units includes a shaft that is associated with a rotating component of the electrostatic process unit such as a toner mixer, a waste auger, a developer, or a photoconductive drum. The shaft includes sealing areas at either end of the shaft that are configured to prevent toner leakage through the sealing areas, and protruding ridges in the sealing areas that encircle the shaft. The protruding ridges are angled relative to the axis of the shaft such that rotation of the shaft causes the protruding ridges to urge stray toner away from the sealing areas. The protruding ridges substantially reduce toner leakage through the sealing areas of rotating shafts of electrostatic process units.

Claim (Index 17):
The electrostatic process unit of  claim 14 , wherein a first subset of angled ridges is displaced inward from a first sealing area on a first end of the shaft, and wherein a second subset of angled ridges is displaced inward from a second sealing area on a second end of the shaft, and wherein each subset of angled ridges is angled so as to directionally urge toner away from an associated sealing area when the shaft is rotated.
