Abstract: A toner cartridge for an electrophotographic image forming device according to one example embodiment includes a housing having a reservoir for storing toner. A rotatable drive shaft is positioned within the reservoir. A partition is mounted on the drive shaft and axially movable along the drive shaft when the drive shaft rotates. The partition divides the reservoir into a first compartment for storing fresh toner and a second compartment for storing waste toner. An expandable agitator is positioned within the second compartment and rotatable with the drive shaft. When the drive shaft rotates and the partition moves along the drive shaft expanding a volume of the second compartment, the agitator expands along a length of the drive shaft and rotates with the drive shaft for agitating waste toner in the second compartment.

Abstract: A toner cartridge according to one example includes a housing having a toner reservoir, an exit for exiting toner and an entry port for receiving waste toner. A partition divides the reservoir into a first compartment for storing fresh toner and a second compartment for storing waste toner. The first compartment is in fluid communication with the exit. The partition is movable within the reservoir between a first position and a second position. The entry port is in fluid communication with the first compartment when the partition is in the first position such that waste toner received through the entry port is deposited into the first compartment. The entry port is in fluid communication with the second compartment but closed off from the first compartment when the partition is in the second position such that waste toner received through the entry port is deposited into the second compartment.
