ABSTRACT:
A cleaning apparatus in a waste toner removal system of an image forming device includes a waste toner moving device that is movably mounted in a waste toner housing. The housing has an inlet where waste toner enters the housing. The toner moving device is movable between a first position and a second position to displace accumulated toner within the housing. The toner moving device is spring-biased toward the first position. A rotating actuator displaces the toner moving device from the first position to the second position to move the toner in the housing away from the inlet. The toner moving device is also self-cleaning via vibration and impact movements.
