A powder material cartridge includes a waste toner chamber that prevents the waste toner from spilling. A receiving section is provided in the chamber and includes a first opening therein through which the powder material is received into the chamber. A first shutter is rotatably received in the receiving section and includes a second opening formed therein. The first shutter is rotatable either to a first opening position where the second opening is in alignment with the first opening, or to a first closing position where the second opening is not in alignment with the first opening. A second shutter is received in the first shutter and is slidable straight in the first shutter. When the second shutter slides to a second closing position, the second shutter closes the second opening. When the second shutter slides to a second opening position, the second shutter opens the second opening.
