An image forming apparatus includes: an image forming apparatus body; an openable member that is supported movably between an opening position and a closing position; a positioning portion that is provided in the image forming apparatus body; a positioned portion that is supported on the openable member and that is brought into contact with the positioning portion to be positioned when the openable member is in the closing position; a rotary member that is supported on the image forming apparatus body; and an opposed member that is supported on the openable member. When the openable member moves to the closing position, the opposed member moves in a direction crossing an opening/closing direction of the openable member and then moves in a reverse direction to the moving direction. And the opposed member is opposed to the rotary member rotatably when the openable member is in the closing position.
