ABSTRACT:
An improved agitator containing toner box for an electrophotographic device that is easier to manufacture and assemble than conventional agitator containing toner boxes. The first of two improvements is that one, instead of two apertures are formed in the toner box to accommodate the agitator shaft. The second improvement is that instead of using bushings inserted into an aperture to prevent toner leakage from the toner box, a cone-shaped seal is placed on the shaft of the agitator and over the aperture to prevent toner leakage through the aperture. These two improvements result in a much simpler and less expensive manufacturing and assembly process.
