PURPOSE:To guide and set up a developing device to/on a prescribed position with a simple constitution by fitting a guide for loading/unloading one developing device to/from a body device to another developing device adjacent to the former developing device and disengaging the guide from the developing device when the developing device is loaded to the body device. CONSTITUTION:When a developing device 6 is guided to an aperture part B on a front side plate A by the guide 20, the device 6 is guided to a prescribed position in the body by a guide rail 26 laid in the body and set up on the position. The guide rail 26 moves the developing device 6 in the arrow direction, a developing device is moved in the side plate of the body independently of the device 6 and only the developing device with a required color is moved to a developing position adjacent to a photosensitive drum. When the device 8 is completely loaded to the inside of the body, a projection part 8a of the device 8 is disengaged from the guides 22a, 22b, independently supported by a guide rail 25 in the body so as to be independently contacted/separated with/ from the drum 1. |
