1. An image forming apparatus to which a developer container is attachable, the developer container provided with a discharge port and a container shutter configured to move for opening/closing the discharge port, the image forming apparatus comprising:
(i) a developer accommodating portion; and
(ii) an attached portion to which the developer container is to be attached in an attaching direction and provided with a receiving port through which the developer accommodating portion is to receive developer from the developer container, the attached portion including,
(ii-i) an operation member configured to move and configured to be operated by a user to move the container shutter, the operation member having an engaging portion configured to engage with the container shutter in a case where the developer container is attached to the attached portion;
(ii-ii) a restriction member configured to move, in a direction intersecting with the attaching direction, between a restricting position in which the restriction member restricts movement of the operation member by engaging with the operation member and an allowable position in which the restriction member allows the movement of the operation member, the restriction member being in the restricting position in a case where the developer container is not attached to the attached portion, wherein the restriction member is configured to move from the restricting position to the allowable position by an attachment of the developer container to the attached portion, and
(ii-iii) a biasing member that biases the restriction member in a direction in which the restriction member is moved from the allowable position to the restricting position.
