<p>PROBLEM TO BE SOLVED: To provide a belt conveyance device and an image forming device, capable of quickly correcting a position in a width direction of a belt by shortening transition time during steering, with a simple configuration.SOLUTION: A belt conveyance device 70 has: an endless belt 7; and a plurality of stretching rollers including a drive roller 71 and a steering roller 72. In a conveyance direction of the belt 7, an image acceptance position I1 is arranged between the drive roller 71 and the steering roller 72. When the stretching roller provided closest to the steering roller 72 out of the plurality of stretching rollers is defined as a closest roller 74, a restraint force in a width direction of the belt 7 between the closest roller 74 and the belt 7 is larger than a restraint force in the width direction of the belt 7 between the steering roller 72 and the belt 7.</p> |
