CONSTITUTION: An image formation device 10 includes an intermediate transfer unit 22, and the intermediate transfer unit has a drive roller 38 and a follower roller 40 pivotally supported by a first frame 52 and the second frame 54, and has an intermediate transfer belt 36 spun to the drive roller and the follower roller. One end of a fixed shaft 68 of the follower roller is movably provided, and other end thereof is fixed to the second frame. A meander detection member 56 and a sleeve 58 are provided coaxially with the follower roller. The sleeve is provided in an interior of the meander detection member. A meandering belt rides over the meander detection unit to thereby rotate the meander detection unit, and the sleeve protrudes. Then, the one end of the fixed shaft moves so as to tilt the fixed shaft. Accordingly, the follower roller is inclined.EFFECT: To allow a meander of a belt to be suppressed without loading an end surface of the belt.SELECTED DRAWING: Figure 3 |
