<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus, in which respective color toner images can be superimposed on one another with higher degree of precision without inviting an increase in cost and a decrease in productivity by a plurality of photoreceptor drums arranged in parallel in the traveling direction of an intermediate transfer belt. <P>SOLUTION: An image forming apparatus 1 includes: a guide part 20 that movably guides exposure devices 124M, 124C, and 124Y in the travelling direction of an intermediate transfer belt 125; and fixing members 22M, 22C, and 22Y that respectively position the exposure devices 124M, 124C,and 124Y to a lower body 111. The respective fixing members 22M, 22C, and 22Y are dilated in the travelling direction of the intermediate transfer belt 125 depending on a temperature change inside the device body by a prescribed length in accordance with the distance from a photoreceptor drum 121 exposed by an exposure device 124B unmovably fixed to the lower body 111, to the respective photoreceptor drums of the exposure devices 124M, 124C, and 124Y. <P>COPYRIGHT: (C)2013,JPO&INPIT |
