ABSTRACT:
An image-forming apparatus includes a developer container containing a developer which is to be inserted into a developer replenisher of a main body, a cover for the developer replenisher and a cover for the developer container. The cover for the developer replenisher and the cover for the developer container are capable of being opened when the developer container is attached to the main body. The image-forming apparatus has a discriminator for discriminating whether the inserted developer container is identified with the developer replenisher. The cover for the developer replenisher and the cover for the developer container are to be opened only when the inserted developer container is identified.
