    • A transfer device has primary transfer rollers supported so as to be upwardly and downwardly movable within a path of movement and opposed to respective of photosensitive drums across a portion of an intermediate transfer belt. There are also provided a slide member for full-color image formation and a slide member for monochromatic image formation, which are capable of reciprocation in a horizontal direction. The transfer device includes roller lifting means each L-shaped and each having one end supporting an associated one of the transfer rollers for rotation and another end engaging an associated one of the slide members, and first and second coaxial rotating cams. The transfer device is capable of switching between three paths of movement of the intermediate transfer belt selectively by the first and second rotating cams rotating together.
    • 传送装置具有支撑的一次转印辊,以便在运动路径内向上和向下移动,并与相应的感光鼓穿过中间转印带的一部分。 还提供了用于全色图像形成的滑动构件和用于单色图像形成的滑动构件,其能够在水平方向上往复运动。 传送装置包括每个L形的滚子提升装置,每个滚子提升装置的一端支撑相关联的一个传送辊,用于旋转,另一端接合相关的一个滑动构件以及第一和第二同轴旋转凸轮。 传送装置能够通过一起旋转的第一和第二旋转凸轮选择性地切换中间转印带的三个运动路径。

    • An forming apparatus of the present invention is provided with a waste-toner transport unit that is installed separately from a photoreceptor drum cartridge. The waste-toner transport unit is pivoted so that the photoreceptor drum cartridge is easily removed from a machine main body. This arrangement makes it possible to miniaturize the photoreceptor drum cartridge and to use the waste-toner transport unit repeatedly. In another image forming apparatus of the present invention, a developer-supplying container, a waste-toner container, and a waste-developer container for receiving excessive developer that has been overflown from the developer tank are integrally formed into a container unit. This arrangement makes it possible to reduce the volumes of the containers in accordance with the respective supplying quantities of developer. Further, a pressing mechanism is provided so that upon replacing the container unit, the developer tank is brought apart from and close to the photoreceptor drum simultaneously with the pivotal movement of the container unit. This arrangement makes it possible to reduce the number of steps that are taken in the replacing operation as well as to prevent misoperations such as caused by negligence of duty in pressing the developer tank toward the photoreceptor.
    • 本发明的成型装置设置有与感光鼓盒分开安装的废色调色剂传送单元。 废料调色剂传送单元被枢转,使得感光鼓盒容易地从机器主体移除。 这种布置使得可以使感光鼓盒小型化并且可以重复地使用废色调色剂传送单元。 在本发明的另一图像形成装置中,用于接收从显影剂罐溢出的过量显影剂的显影剂供应容器,废料调色剂容器和废弃显影剂容器一体地形成为容器单元。 这种布置使得可以根据显影剂的相应供应量来减小容器的体积。 此外,提供一种按压机构,使得在更换容器单元时,与容器单元的枢转​​运动同时,显影剂罐与感光鼓分离并靠近感光鼓。 这种布置使得可以减少在更换操作中采取的步骤数量,并且可以防止由于将显影剂罐压向感光体时的工作过重而导致的误操作。
