An image forming apparatus includes an image forming unit, a first main body frame and a second main body frame, a sheet placing portion, a feed roller, a link arm and a bridge frame. The feed roller moves with the link arm. The bridge frame is configured to join the first main body frame with the second main body frame and to swingably support the link arm. The link arm is movable between a temporary mounting position, in which the entirety of the link arm is positioned between the first main body frame and the second main body frame, and a final mounting position, in which the link arm is supported by the bridge frame and cooperates with the feed roller. At least one of the link arm and the bridge frame is positioned with holding mechanism configured to hold the link arm in the temporary mounting position.
