<P>PROBLEM TO BE SOLVED: To stably correct the meandering of an endless belt by a simple mechanism. <P>SOLUTION: An intermediate transfer unit 50 includes: an intermediate transfer belt 51 which does not have elasticity; an intermediate transfer belt tension roller 54; a shaft member 21; deviation transmitting members 25A and 25B; and energizing members 26A and 26B. The deviation transmitting members 25A and 25B are inserted in the shaft member 21 so as to be respectively adjacent to both end portions in an axial direction 101 of the intermediate transfer belt tension roller 54. The deviation transfer member disposed at least on a downstream side in a deviation direction along the axial direction 101 of the deviation transmitting member 25A and 25B, moves along the shaft member 21 with the intermediate transfer belt 51. The energizing members 26A and 26B are journaled by the deviation transmitting members 25A and 25B at action end portions, and journaled by device frames 22A and 22B at base end portions at predetermined positions on the end portion side in the axial direction 101 rather than the action end portions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
