Claim:
A waste developer collecting container which is used in an image forming apparatus and can be removed therefrom and stores developer particles which, of the developer used for developing images of information formed on an electrostatic latent image bearing member, have not been transferred to a recording medium and have been collected as waste developer, wherein an air sealing member is disposed at the coupling between the waste developer collecting container and a conveying member for conveying the collected waste developer into the waste developer collecting container through a collecting port to prevent the waste developer from spilling out at the coupling when the waste developer is conveyed and to seal the collecting port so that no waste developer will spill out from the waste developer collecting container which has been removed for replacement after the waste developer collected and conveyed therein by the conveying member has reached a predetermined amount, the waste developer collecting container can be reused by attaching a new air sealing member around the collecting port of the waste developer collecting container, and the air sealing member comprises a seal, an adhesive and a waste developer anti-scatter member made of a foaming or an elastic element, laminated in the order mentioned, from the waste developer collecting container side to the opposite side in the coupling.
