PURPOSE: To facilitate assembling, maintenance and the change of components or the like around an image forming body by making the image forming body integrally attachable to and detachable from an electrifying device, an image exposure means and a developing device and transmitting rotation from the image forming body to respective developing devices. CONSTITUTION: The electrifying device, the image exposure means 4Y to 4K, the developing devices 5Y to 5K and a cleaner are disposed at a unit frame 30 easily attached and detached to/from a device main body. thus, the position adjustment, the assembling, the maintenance and the change or the like of the image forming body 1 and the electrifying device, the image exposure means 4Y to 4K and the developing device 5Y to 5K or the like around the body 1 are easily and surely performed. Since the rotation is transmitted from the image forming body 1 to the developing devices 5Y to 5K, the driving and controlling of the developing devices 5Y-5K is easily performed. Toner is carried by a carrying screw 2b without being accumulated and is dropped in a waste toner container on the side of a lower frame from a drop tube 2c so as to assemble the cleaner in the unit frame 30, so that it is miniaturized. |
