ABSTRACT:
A toner cartridge with a uni-body construction reduces the cost of production as well as reducing the chance of failure during use. The toner cartridge includes a waste bin having a leading end that can be sculpted to mate with the cartridge-receiving cavities of a large number of printers. Additional improvements include an improved toner sifting agitator. The sifting action ensures that toner stays sufficiently fluid, and distributes evenly on the toner adder roller.
