Abstract: Provided is an image forming apparatus in which a movable member comes close to an opening to cover a part of the opening in the open state of an opening and closing member. In the course of change from the open state to the state in which an entering portion enters the inside of the housing, the movable member is pressed by the entering portion to move away from the opening and the opening and closing member moves toward the opening. In the closed state of the opening and closing member, the movable member is placed in a position further away from the opening than in the open state, and the opening and closing member is in the position in which the opening and closing member covers a part of the opening while forming a gap between the opening and closing member and the housing.
