1. An image forming apparatus comprising:
a guide that is a component of a conveyance route for a print medium; a first door that incorporates the guide, an inside of the conveyance route being exposed to an outside of a main body of the image forming apparatus when the first door is open; a functional component fixed to the first door, the functional component being placed in a specified position by contact with a component located inside the main body when the first door is closed; a first lock mechanism for keeping the first door closed, wherein the first lock mechanism comprises: a first catching part formed in the main body; a second catching part fitted to the first door, the second catching part engaging with the first catching part when the first door is closed; and a first lever for disengagement of the first catching part and the second catching part from each other; a second door that covers the first door when the second door is closed and that exposes the first door to the outside of the main body when the second door is open; and a second lock mechanism for keeping the second door closed, wherein the second lock mechanism comprises: a third catching part formed in the main body; a fourth catching part fitted to the second door, the fourth catching part engaging with the third catching part when the second door is closed; and a second lever for disengagement of the third catching part and the fourth catching part from each other; wherein a closing motion of the second door in a state wherein both the first door and the second door are open activates the second lock mechanism and the first lock mechanism, whereby the first door is put closed; and wherein when the second lever is handled in a state wherein both the first door and the second door are closed, but the first and second lock mechanisms are not engaged, the third catching part and the fourth catching part are caused to engage with each other, and the first lever is moved by the second lever to cause the first catching part and the second catching part to engage with each other.
