  • Color image-forming apparatus adapted to stabilize contact between endless belt-like photosensitive medium and developing roller
    Patent number: 5671467
    Abstract: A color image-forming apparatus includes an endless belt-like photosensitive member stretched between and wound around a drive roller and a driven roller, and a plurality of developing rollers making contact with an outer surface of the photosensitive member. At least one flexure correction shaft is held in contact with an inner surface of the photosensitive member on the side remote from the developing rollers. With this construction, the condition of contact between each developing roller and the photosensitive member is made stable and uniform, and the developing conditions for all the colors become uniform so that a high-quality image can be obtained.
