1. A toner cartridge, comprising:
a housing having a top, a bottom, a first side and a second side positioned between a first longitudinal end and a second longitudinal end of the housing, the housing has a reservoir for holding toner;
a first drive coupler and a second drive coupler on the first longitudinal end of the housing for mating with a first corresponding drive coupler in an image forming device and a second corresponding drive coupler in the image forming device for receiving rotational motion from the first corresponding drive coupler in the image forming device and the second corresponding drive coupler in the image forming device when the toner cartridge is installed in the image forming device, the first drive coupler of the toner cartridge has a first rotational axis and the second drive coupler of the toner cartridge has a second rotational axis, the first rotational axis of the first drive coupler of the toner cartridge is positioned higher than the second rotational axis of the second drive coupler of the toner cartridge; and
a latch-receiving shelf on the first longitudinal end of the housing, the latch-receiving shelf is unobstructed from above permitting the latch-receiving shelf to contact a corresponding hold-down in the image forming device and receive a downward hold-down force from the corresponding hold-down in the image forming device when the toner cartridge is installed in the image forming device, the latch-receiving shelf is positioned lower than the first rotational axis of the first drive coupler of the toner cartridge and the latch-receiving shelf is positioned higher than the second drive coupler of the toner cartridge,
wherein an imaginary vertical plane extending along a longitudinal dimension of the housing that runs from the first longitudinal end to the second longitudinal end intersects the latch-receiving shelf and the second drive coupler of the toner cartridge.
