PROBLEM TO BE SOLVED: To improve positional accuracy between a plurality of fist processing units, as well as positional accuracy between an image forming unit having the first processing units and an intermediate transfer unit.SOLUTION: A unit assembly 10 includes an image forming unit 20 and an intermediate transfer unit 40, and can be attached to/detached from a device body 110. The image forming unit 20 includes first processing units 200A-200D, developing units 4A-4D, a positioning part, and a joining member 80. The positioning part is disposed in each of the developing units 4A-4D, to relatively position the developing units 4A-4D. The joining member 80 joins the developing units 4A-4D. The intermediate transfer unit 40 is held by the image forming unit 20. |
