<P>PROBLEM TO BE SOLVED: To prevent the deviation of an endless member by a simple configuration. Ž<P>SOLUTION: The endless member driving device (BM) includes: a deviation detecting member (13) rotatably supported at the axial end of a rotating support member (Rj) supporting the endless member (B); and a shaft position changing member (14) which is rotatably supported at the axial end of the rotating support member (Rj) and rotatable based on the rotation of the deviation detecting member (13) when the endless member (B) is deviated toward the axial end of the rotation shaft (Rj1), and the deviation detecting member (13) receives a force from the endless member (B), the shaft position changing member (14) having an outer circumferential surface that changes in length to the radially outside edge relative to the rotation shaft (Rj1) of the rotating support member (Rj) and configured in such a manner that the outer circumferential surface comes in contact with a reference face (18) to change the position of the rotation shaft (Rj1) of the rotating support member (Rj) in the direction in which the deviation of the endless member (B) is corrected.
