    • An image forming apparatus includes a photosensitive body on which a visible image is developed by developer, an intermediate transfer belt to which developer of the photosensitive body is transferred, and a first transfer roller to transfer the developer from the photosensitive body to the intermediate transfer belt, wherein since a developing unit housing at which the photosensitive body is mounted is provided with position regulating guides to support a shaft of the first transfer roller, the intermediate transfer belt comes into contact with the photosensitive body at a uniform angle. As a result, uniform print quality may be obtained.
    • 图像形成装置包括:感光体,其上由显影剂使可见图像显影;感光体的显影剂被转印到的中间转印带;以及第一转印辊,用于将显影剂从感光体转印到中间转印带 其中,由于安装有感光体的显影单元壳体设置有位置调节引导件,以支撑第一转印辊的轴,所以中间转印带与感光体以均匀的角度接触。 结果,可以获得均匀的打印质量。

    • An image forming apparatus and a transfer device thereof the transfer device including an intermediate transfer belt, at least one intermediate transfer belt roller to maintain tension in the intermediate transfer belt, transfer rollers to press the intermediate transfer belt to image carriers and a state changing device. The state changing device includes: a rotating shaft; a first cam member coupled to the rotating shaft and configured to move the intermediate transfer belt roller to reduce the tension applied to the intermediate transfer belt; and a second cam member coupled to the rotating shaft and configured to move at least one of the transfer rollers away from the intermediate transfer belt.
    • 一种图像形成装置及其传送装置,其包括中间转印带,至少一个中间转印带辊,用于保持中间转印带中的张力,转印辊将中间转印带按压到图像载体和状态改变装置 。 所述状态改变装置包括:旋转轴; 第一凸轮构件,其联接到所述旋转轴并且构造成移动所述中间转印带辊以减小施加到所述中间转印带的张力; 以及第二凸轮构件,其联接到所述旋转轴并且构造成使所述转印辊中的至少一个远离所述中间转印带。
