A supply container attachable to a cartridge, the supply container comprising:
- a frame configured to contain toner, the frame having an ejection port for ejecting toner contained in the frame;
- a pushing member attached to the frame, the pushing member being configured to be movable in a first direction, relative to the frame, from a first position to a second position, such that the toner contained in the frame is ejected through the ejection port when the pushing member is moved in the first direction;
- and
- a movement restriction portion including a first part provided in one of the pushing member and the frame and a second part provided in an other one of the pushing member and the frame, the first part and the second part being brought in contact with each other to restrict movement of the pushing member in the first direction when the pushing member is located at an intermediate position between the first position and the second position, wherein
- in a state where the pushing member is located at the intermediate position, the pushing member is configured to be movable relative to the frame such that the first part and the second part separate from each other.
