Abstract
A belt driving apparatus includes an endless belt which is wrapped around at least a driving roller and a driven roller, a belt shift detecting member detecting a shift of the endless belt and being rotatably supported by the driven roller with at least one end of a shaft thereof, the belt shift detecting member rotating free from a rotation of the driven roller, a supporting device supporting the at least one end of shaft of driven roller and being moveable in a direction perpendicular to a direction of the shaft of the driven roller, and a conversion device converting a displacement of said at least one end of the shaft of the driven roller into a displacement in a predetermined direction perpendicular to shaft of the driven roller, when the endless belt is brought into contact with the belt shift detecting member and belt shift detecting member has a rotation torque. The conversion device includes a secured member which is mounted on a main body side of the apparatus, arranged to contact a part of the belt shift detecting member when the belt shift detecting member rotates to a predetermined angle caused by the rotation torque, and a cam converting a movement of the belt shift d…
