Abstract
Toner cartridge includes a housing, an agitator, an auger, a first protrusion, and a second protrusion. The housing includes a first toner accommodating portion having and a second toner accommodating portion. The auger is rotatable about a second axis extending in a first direction and is configured to convey toner from a first toner accommodating portion to the second toner accommodating portion. The first protrusion is positioned at a first side of the second toner accommodating portion. The first protrusion extends in the first direction. The second protrusion is positioned at a second side of the second toner accommodating portion and extends in the first direction.
Claims19
A toner cartridge comprising:
- a housing accommodating toner, the housing having a first opening allowing toner to be discharged therefrom;
- an auger rotatable about a first axis extending in a first direction, the auger configured to convey the toner to the first opening in the first direction, the auger having one end portion and another end portion positioned apart from the one end portion in the first direction;
- a first protrusion extending in the first direction, the first protrusion being positioned closer to the one end portion of the auger than the another end portion of the auger is to the one end portion of the auger, the first protrusion being rotatable relative to the housing;
- and
- a second protrusion extending in the first direction, the second protrusion being positioned closer to the another end portion of the auger than the one end portion of the auger is to the another end portion of the auger,
- wherein when the toner cartridge is mounted to a developing unit, the housing is pivotable relative to the developing unit about the first protrusion,
- wherein the auger is positioned between the first protrusion and the second protrusion in the first direction, and
- wherein when the toner cartridge is mounted to the developing unit, the housing is pivotable relative to the developing unit about the first protrusion and the second protrusion.
A toner cartridge comprising:
- a housing accommodating toner, the housing having a first opening allowing toner to be discharged therefrom;
- an agitator rotatable about a first axis extending in a first direction, the agitator configured to agitate the toner in the housing;
- an auger rotatable about a second axis extending in the first direction, the auger configured to convey the toner to the first opening in the first direction, the auger spaced apart from the agitator in a second direction crossing the first direction;
- a first protrusion extending in the first direction, the first protrusion positioned at one side of the housing in the first direction;
- and
- a second protrusion extending in the first direction, the second protrusion positioned at another side of the housing in the first direction,
- wherein the auger is positioned between the first protrusion and the second protrusion in the first direction, and
- wherein a first width of the first protrusion in a third direction crossing the first direction and the second direction is different from a second width of the second protrusion in the third direction.
