    • 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。

    • A waste toner collecting system in an image forming apparatus which forms on the surface of an image carrier an electrostatic latent image corresponding to an original image, develops the latent image with toner and transferrs the toner image onto a copy material. The waste toner collecting system comprises a cleaning unit for removing residual toner from the image carrier after the toner image has been transferred, a container, independent of the cleaning unit, for storing the removed waste toner, and a transport device for conveying the waste toner removed by the cleaning unit to the container, with an outlet formed in the toner transport device so as to discharge the waste toner, a waste toner inlet formed in the container at a position corresponding to the outlet in the toner transport device, and shutter members provided for the outlet and the inlet, respectively, the shutter members being opened or closed according to as the waste toner container is mounted or dismounted.
    • 在图像形成装置的表面上形成与原始图像对应的静电潜像的图像形成装置中的废粉收集系统,利用调色剂显影潜像并将调色剂图像转印到复印材料上。 废粉收集系统包括清洁单元,用于在转印调色剂图像之后从图像载体去除残留调色剂,独立于清洁单元的容器用于储存除去的废调色剂,以及用于输送废调色剂的输送装置 由清洁单元移除到容器上,其中出口形成在调色剂输送装置中以便排出废调色剂,在与调色剂输送装置中的出口相对应的位置处形成在容器中的废调色剂入口以及挡板部件 根据作为废调色剂容器的安装或拆卸,分别为出口和入口提供活门构件的打开或关闭。

    • Support structures for containing and supporting components forming a digital copier are configured with square pipes and are provided separately in association with a plurality of units of the digital copier. The effect of distortion is eliminated when the support structures are joined to maintain positional accuracy. Square pipes are combined to form each of a first support structure for containing and supporting various components forming the digital copier, for example, an image forming process portion and a fixing portion and a second support structure for containing and supporting various components to be incorporated therein as needed, for example, a sheet supplying portion. To combine the first and second support structures, square pipes and square pipes orthogonal to each other are joined in the regions of joining surfaces. This makes it possible to prevent, for example, distortion and twisting between the supporting structures.
    • 用于容纳和支撑形成数字复印机的部件的支撑结构被配置为方管,并且与数字复印机的多个单元相关联地提供。 当连接支撑结构以保持位置精度时,消除了变形的影响。 方形管组合形成用于容纳和支撑形成数字复印机的各种部件的第一支撑结构中的每一个,例如图像形成处理部分和固定部分,以及用于容纳和支撑待并入其中的各种部件的第二支撑结构 根据需要,例如,片材供给部。 为了组合第一和第二支撑结构,在连接表面的区域中连接彼此正交的方管和方管。 这使得可以防止例如支撑结构之间的扭曲和扭曲。
