    • PROBLEM TO BE SOLVED: To provide a sheet material position correction device in which the width direction position of a driven roller with respect to the drive roller is corrected within a short time without largely deviating, even though it is configured in such a manner that a conveyance roller pair which comprises a drive roller and a driven roller for holding and conveying a sheet material is provided, and the driven roller can be driven in the width direction according as moving means moves the drive roller in the width direction; and an image forming apparatus.SOLUTION: Moving means moves a drive roller 33A toward a moving direction of either one end side of the width direction or the other end side of the width direction, and corrects the width direction position of the sheet material; thereafter, in a state where the sheet material is not held, moves a drive roller 34A in the reverse direction with respect to the moving direction until a driven roller 33B in a state where its width direction position is deviated becomes abutted against a stopper part 36a1, and even after that, further moves the drive roller 33A in the reverse direction to a prescribed position with the driven roller 33B being abutted against the stopper part 36a1.
    • 要解决的问题:为了提供一种片材材料位置校正装置,其中从动辊相对于驱动辊的宽度方向位置在短时间内被校正而没有大的偏差,即使其被构造成使得 提供包括驱动辊和用于保持和输送片材的从动辊的输送辊对,并且随着移动装置沿宽度方向移动驱动辊,从动辊可沿宽度方向驱动; 和图像形成装置。解决方案:移动装置使驱动辊33A朝向宽度方向的一端侧或宽度方向的另一端侧的移动方向移动,并校正片材的宽度方向位置; 此后,在没有保持片状材料的状态下,驱动辊34A相对于移动方向沿相反方向移动,直到在其宽度方向位置偏离的状态下的从动辊33B抵靠止动件36a1 并且即使此后,驱动辊33A在从动辊33B抵靠止动部36a1的同时使反作用力进一步移动到规定位置。
