Abstract
A system and method for cooling electrostatic process units includes an impeller in communication with a shaft associated with a rotating component of the electrostatic process unit such as a toner mixer, a waste auger, a developer, or a photoconductive drum. When the shaft rotates, the impeller rotates and causes air to be directed into a cooling duct. The cooling duct directs the air over one or more components of the electrostatic process unit such as the developer or a doctor blade. The air directed over the components cools the electrostatic process unit.
