PROBLEM TO BE SOLVED: To provide an image forming device that prevents skew of an intermediate transfer belt.SOLUTION: An image forming device 1 includes: an image forming part having a photoreceptor 41; an intermediate transfer intermediate transfer belt 51 facing the photoreceptor 41; an intermediate transfer belt attitude change part 71; a steering roller 58; an adjustment roller 59; and an adjustment part moving mechanism. The intermediate transfer belt attitude change part 71 brings a part of the intermediate transfer belt 51 into contact with the photoreceptor 41 or separates them from each other. The steering roller 58 has the intermediate transfer belt 51 stretched thereon, adjusts a position of the intermediate transfer belt 51, and applies tension to the intermediate transfer belt 51. The adjustment roller 59 is arranged in a position adjacent to the steering roller 58 in a circumferential direction of the intermediate transfer belt 51, and has the intermediate transfer belt 51 stretched thereon. The adjustment part moving mechanism moves the adjustment roller to a position where a winding angle of the intermediate transfer belt 51 relative to the steering roller 58 does not change, according to an attitude of the intermediate transfer belt 51. |
