PROBLEM TO BE SOLVED: To hold a pressing lever in the state of being inclined toward this side without disposing an urging means by composing so that with the pressing lever put at a second position, the spring force of a pressing spring means acts in the direction where the pressing lever is held at the second position. SOLUTION: The pressing lever 240, in the state of being put in the second position in which it is horizontal, is almost at the same height as the top face of a movable placing plate 220. Therefore, because, with the pressing lever 240 put at the second position, a developing device can be attached/detached to/from the movable placing plate 220, and the pressing lever 240 functions as a guide terrace when the developing device is attached/detached. The pressing lever 240 put at the second position, which has the function of the guide terrace, is urged so as to be held at the second position by means of extension coil springs 208, thus, it is prevented from rattling and made stable, and the attachment/detachment of the developing device becomes easy and simple. |
