A cartridge that can be detachably mounted in an image-forming device, the cartridge comprising:
- a first wall:
- a second wall opposing the first wall with a gap formed therebetween, the first wall and the second wall defining therebetween a developer-accomodating section that accommodates a developer, wherein the developer-accomodating section has a discharge opening formed to discharge developer;
- a reinforcing part spanning between the first wall and the second wall;
- an agitator that is disposed in t e developer-accommodating section and is driven to rotate to stir the developer, wherein the reinforcing part is positioned out of contact with the rotating agitator and the agitator is positioned near the discharge opening;
- and
- two side walls facing each other along the axial direction of the agitator and being separate from each other, wherein a distance between the side walls at a first position where the agitator is disposed is shorter than a distance between the side walls at a second position on the opposite side of the agitator from the discharge opening.
