摘要：PROBLEM TO BE SOLVED: To provide an image formation device capable of suppressing looseness of a first photosensitive drum and a second photosensitive drum.SOLUTION: A direct tandem type color printer 1 includes a plurality of photosensitive drums 11 corresponding to each color of yellow, magenta, cyan, and black. A bearing 30 which pivots the plurality of photosensitive drums 11 is provided with elastic parts 53, 63 which pressurize a corresponding photosensitive drum 11 in a radial direction. An elastic force of the elastic parts 53, 63 of the bearing 30 which pivots a yellow photosensitive drum 11Y arranged in top stream in a transportation direction of paper P is set larger than that of the elastic parts 53, 63 of the bearing 30 that pivots a magenta photosensitive drum 11M, a cyan photosensitive drum 11C, and a black photosensitive drum 11K which are in a lower stream than the yellow photosensitive drum 11Y.
