An image forming apparatus includes an apparatus body, a developer container, an outlet, a first shutter, a cover member, a movable member, and a transmission member. The developer container is removably mountable relative to the apparatus body through an opening. The first shutter opens and closes the outlet. The cover member opens and closes the opening. The movable member is reciprocally movable in forward and reverse directions. The transmission member transmits action of the cover member to the movable member and is disposed between the cover member and the movable member. When the movable member is moved in the forward direction, the first shutter is closed. When the movable member is moved in the reverse direction, the first shutter is opened. In a terminal period of an opening operation of the cover member, a movement direction of the movable member is reversed from the forward direction to the reverse direction.
