ABSTRACT:
A steering mechanism moves an intermediary transfer belt in its width direction by moving an inclination angle of two steering rollers with respect to a rotational direction of the intermediary transfer belt. The two steering rollers changes the inclination angle while maintaining a rectangle defined by the steering rollers and bearing arms to ensure a thrust movement distance in a period from start of winding of one of the steering rollers and end of winding of the other steering roller.
