    Abstract: An example toner refill cartridge includes a body, a plunger, a weight part, and a weight part container. The body includes a toner chamber to contain toner and a toner discharging portion having an entrance connected to one end of the toner chamber in a length direction and an exit to discharge toner. The plunger includes a piston that is movably inserted into the toner chamber in the length direction and a packing member located at an end of the piston to push the toner toward the toner discharging portion. The weight part is movably accommodated in the toner chamber and has a shape that prevents the weight part from passing through the entrance. The weight part container is provided in the one end of the toner chamber in the length direction such that the weight part can be accommodated therein.
