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.
Claims6
An apparatus comprising:
- a rotatable belt member;
- a rotatable supporting member for supporting said belt member;
- a first rotatable steering member for adjusting a position of said belt member with respect to a rotational axis direction of said supporting member by contacting an inner surface of said belt member and inclining with respect to the rotational axis direction of said supporting member;
- a second rotatable steering member for adjusting the position of said belt member with respect to the rotational axis direction of said supporting member by contacting the inner surface of said belt member and inclining with respect to the rotational axis direction of said supporting member;
- a connecting portion for connecting said first rotatable steering member and said second rotatable steering member with each other;
- and
- an interrelating mechanism for interrelating an inclining operation of said first rotatable steering member and an inclining operation of said second rotatable steering member with each other so that said first rotatable steering member and said second rotatable steering member incline in the same direction by said connecting portion.
