PROBLEM TO BE SOLVED: To easily attach/detach an image forming body and an image exposing means to/from a device main body by enabling to attach/detach then as one body and attaching/detaching them retreating developing devices. SOLUTION: A side plate 22 is installed in the main body 10, and the developing device 40M and an electrostatic charger 45M can be moved as one body to the left in the figure at the time of attaching/detaching the unit 92. In the same way, the developing device 40Y can be moved to the left. And also, the developing device 40C and the electrostatic charger 45C can be moved as one body to the right, and in the same way, the developing device 40K is also moved to the right. On the other hand, the image forming body 20, the image exposing means and a shaft 21 are installed in the unit 92. As for the fixation of the unit 92, the shaft 21 is fitted into a U-shaped groove of the device main body and pressed downward, then, the unit 92 is fixed by a locking member 23 equipped with a shaft 25. Besides, the locking member 23 is energized by a spring 24. |
