    • A fixing device has a web unit with a housing having two shaft members in parallel with each other, the housing defining a through hole on each of two lateral sides of the housing. The web unit also has a web member windably supported by the two shaft members, and a handle having two protrusion protruded from a lateral surface of the housing to outside of the housing. Each of the two protrusions defines a first width and a second width larger than the first width. The fixing device also has a fixing device frame to be detachably disposed to the web unit. The fixing device frame has a guiding groove with a groove through which the two protrusions are guided on the basis of the first width, and a guiding portion at an end of the groove to allow the two protrusions to be changed from the first width to the second width. The attachment or detachment of the web unit to or from the fixing device frame is regulated corresponding to a position of the handle with respect to the housing.
    • 固定装置具有腹板单元,所述腹板单元具有彼此平行的两个轴构件的壳体,所述壳体在所述壳体的两个横向侧面中的每一个上限定通孔。 腹板单元还具有由两个轴构件可转动地支撑的腹板构件,以及具有从壳体的侧表面突出到壳体外部的两个突起的手柄。 两个突起中的每一个限定第一宽度和大于第一宽度的第二宽度。 定影装置还具有可拆卸地设置在幅材单元上的定影装置框架。 定影装置框架具有带槽的引导槽,基于第一宽度引导两个突起,并且在槽的端部处的引导部分允许两个突起从第一宽度改变为 第二宽度。 根据手柄相对于外壳的位置,调节卷筒单元与固定装置框架的连接或拆卸。

    • An image forming apparatus includes a developing unit having a photoreceptor, for making an electrostatic latent image on a surface of the photoreceptor visible as a toner image. A toner hopper stores toner to be supplied to the developing unit and a cleaning device removes and recovers the toner remaining on the surface of the photoreceptor after the toner image has been transferred onto a recording material. A toner transporting passage is connected between the cleaning device and the toner hopper, through which the toner recovered by the cleaning device is returned to the toner hopper. A toner exhausting port is disposed at a part of the toner transporting passage, from which the toner being returned from the cleaning device side is exhausted outside the toner transporting passage. An opening and closing member selectively opens or closes the toner exhausting port, wherein an inner diameter of the toner exhausting port is made larger than that of the toner transporting passage.
    • 图像形成装置包括具有感光体的显影单元,用于使感光体的表面上的静电潜像作为调色剂图像可见。 调色剂料斗存储要供应到显影单元的调色剂,并且清洁装置在调色剂图像转印到记录材料上之后,去除和回收残留在感光体表面上的调色剂。 调色剂输送通道连接在清洁装置和调色剂料斗之间,由清洁装置回收的调色剂返回到调色剂料斗。 调色剂排出口设置在调色剂输送通道的从清洁装置一侧返回的调色剂从调色剂输送通道的外部排出的部分。 打开和关闭构件选择性地打开或关闭调色剂排出口,其中调色剂排出口的内径大于调色剂输送通道的内径。
