ABSTRACT:
In an intermediate transfer part (100), a bead107is formed on an inner side of an intermediate transfer belt (102), which is rotated by an intermediate transfer belt drive roller (101). Driven roller bearings (104a, 104b) support an intermediate transfer belt driven roller (103). The intermediate transfer belt driven roller (103) is movable in a thrust direction. Ends of the intermediate transfer belt driven roller (101) and the intermediate transfer belt driven roller (103) interfere with a bead (107) so as to restrict a deflection of the intermediate transfer belt in the thrust direction. The intermediate transfer belt driven roller (103) is movable in the thrust direction against a deflection of the intermediate transfer belt (102).
