PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing a user or the like from erroneously taking out an image forming unit from a unit holding part in device structure where a plurality of image forming units are attachably/detachably held by the unit holding part so as to be exchanged. SOLUTION: A side plate 32 is arranged on the take-out side of a rotary developing part 3, and a port exclusively used for taking out 321 is provided on the plate 32. Only when the developing unit is positioned at a place exclusively used for taking out, the developing unit can be taken out through the port 321. While the developing unit is positioned at a place other than that exclusively used for taking out, the taking out the developing unit is regulated by the side plate 32. Then, the black developing unit 3K is not taken out until it is positioned at the place exclusively used for taking out. |
