PROBLEM TO BE SOLVED: To prevent damage for a sleeve, which is caused by being rubbed, by enabling the actuation of a pressing lever at a first position where it is higher than the placing face of a movable placing plate and at a second position where it is almost at the same height as the placing face of the movable placing plate. SOLUTION: With the pressing lever 24 put at the first position in which it is vertical, a lever part 241 is higher than the top face of the movable placing plate 220. Therefore, with the pressing lever 240 put at the first position, the attachment/detachment of a developing device to/from the movable placing plate 220 is not allowed. On the other hand, with the pressing lever 240 put at the second position in which it is horizontal, it is almost at the same height as the top face of the movable placing plate 220. Therefore, with the pressing lever 240 put at the second position, the attachment/detachment of the developing device to/from the movable placing plate 220 is allowed. Thus, by carrying out the attachment/detachment of the developing device at the pressing position, damage for the sleeve member is prevented. |
