摘要： PROBLEM TO BE SOLVED: To prevent an occurrence of an abnormal image due to slip between a belt-like member and a driving roller and a secondary transfer roller by maintaining a proper tension and length of the belt-like member wound on a driving roller even when the belt length is varied without enlarging a machine or giving a curling tendency to the belt-like member even when not used for a long time.
SOLUTION: A roller shaped rotating body (pressing member) 50 is arranged adjacent to the driving roller 21. The rotating body is pressed to an intermediate transfer belt by being energized by an energizing member, etc, in the direction f which is in parallel to the direction of stretching the intermediate transfer belt (belt-like member) 20 between the rotating body and the driven roller.
