PROBLEM TO BE SOLVED: To realize the maintenance of an image carrier unit and a developing unit while restraining the lowering of the strength of a device main body and to avoid the deterioration of image quality even in the case of long-term use. SOLUTION: An intermediate transfer belt is arranged between a 1st image forming part for forming a color image and a 2nd image forming part for forming a black-and-white image. The 1st image forming part is provided to slide in an R-S direction through the aperture part 37 on the front of the device main body. Meanwhile, the 2nd image forming part is provided to slide in a P-Q direction through an aperture part 35 on the side surface of the device main body. By making the sliding direction of both the 1st and the 2nd image forming parts different, the aperture part 37 provided in the R-S direction is formed to be smaller than in constitution that both of the 1st and the 2nd image forming parts are made to slide in the R-S direction. |
