  • Belt conveyance apparatus and image forming apparatus using such a belt conveyance apparatus
    Patent number: 7623816
    Abstract: In an intermediate transfer part (100), a bead 107 is 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).
