ABSTRACT:
A toner cartridge includes a hopper having two inclined lower surfaces. A toner outlet port is formed in one of the lower surfaces. A toner-supplying auger is located within the toner cartridge near the lower surfaces to guide toner. A toner-receiving plate is loosely mounted on the inclined lower surfaces of the hopper to be vibrated. This plate has an opening through which the toner may fall from the hopper onto the auger. Two pins protrude from the periphery of the auger. As the auger is rotated, the pins strike the toner-receiving plate, thus vibrating the plate. As the plate is vibrated, the resultant stirring guides the toner to the opening. The toner guiding means are arranged to substantially superpose the lower surfaces of the cartridge.
