Image-forming device and developer material unit having waste developer material accommodating part

A developer material unit for being detachably mounted in an image-forming device, the developer material unit comprising:

• a developer material accommodating part that is configured to accommodate developer material for being used for image formation executed in the image-forming device;
• a waste developer material accommodating part that is provided integrally with the developer material accommodating part and that is configured to accommodate waste developer material to be discarded from the image-forming device;
• and
• a waste developer material conveying member that is disposed outside the waste developer material accommodating part and that is coupled to the waste developer material accommodating part, while being movable relative to the waste developer material accommodating part, to convey the waste developer material to the waste developer material accommodating part, the waste developer material conveying member being movable relative to the waste developer material accommodating part between a first relative position and a second relative position, the waste developer material conveying member located at the first relative position being further away from the waste developer material accommodating part than the waste developer material conveying member located at the second relative position,
• wherein the waste developer material conveying member comprises:
• a main body part configured to convey the waste developer material in a first direction;
• and
• a connecting part that extends from the main body part in a second direction orthogonal to the first direction and connects to the waste developer material accommodating part.
