    • A developing unit includes a developing tank and a toner hopper. The developing tank is disposed to oppose a recording medium rotatably mounted to an image forming apparatus utilizing electrophotography. A developing member conveys a developer and attaches toner to an electrostatic latent image formed on the recording medium to develop the electrostatic latent image. The toner hopper has a toner supply port for supplying toner to the developing tank through a toner replenishing port formed in the developing tank. The developing tank is detachable in a direction of a rotating shaft of the recording medium, and is movable in a direction perpendicular to the direction of the rotating shaft of the recording medium so as to separate from or oppose the recording medium. The toner hopper has a shutter for opening/closing an opening of the toner supply port. A moving mechanism mounted on the developing tank simultaneously provides movement of the developing tank in the direction perpendicular to the direction of the rotating shaft of the recording medium and movement of the toner hopper shutter to open/close the toner supply port when manipulated.
    • 显影单元包括显影槽和调色剂料斗。 显影槽设置成与可旋转地安装到使用电子照相术的图像形成装置的记录介质相对。 显影构件输送显影剂并将调色剂附着在形成在记录介质上的静电潜像上以显影静电潜像。 调色剂料斗具有用于通过形成在显影槽中的调色剂补充口向显影槽供给调色剂的调色剂供给口。 显影槽可以在记录介质的旋转轴的方向上拆卸,并且可以在与记录介质的旋转轴的方向垂直的方向上移动,以便与记录介质分离或与记录介质相对。 调色剂料斗具有用于打开/关闭调色剂供给口的开口的快门。 安装在显影槽上的移动机构同时提供显影槽在与记录介质的旋转轴的方向垂直的方向上的移动,并且当操纵时调色剂料斗快门的运动打开/关闭调色剂供给口。

    • A developing device of an electrophotographic copier is structured separably into two mutually attachable and internally connected sections. One of these sections is disposed adjacent to the copier's photoreceptor and contains a developing roller and the other section distal from the photoreceptor is made of a relatively inexpensive synthetic resin material, including a stirrer roller. When the developing agent is spent, the two sections are separated and only the second part with the stirring roller is discarded for replacement. In order that the spent developing agent can be effectively collected, a bar magnet may be inserted into a chamber formed inside the shaft of the stirrer roller to make use of its magnetic force or a scrapper may be provided to scrape off the developing agent remaining attached to the developing roller. In the case of a clam shell type copier with a top part of the main body made openable rotatingly with respect to its base part, the developing device becomes tilted when the copier is opened for its replacement. A device for shaking the tank can effectively cause the developing agent remaining inside to move into the lower section of the device for easy collection.
    • 电子照相复印机的显影装置可分离地构成两个相互连接和内部连接的部分。 这些部分中的一个设置在复印机的感光体附近并且包含显影辊,并且远离感光体的另一部分由相对便宜的合成树脂材料制成,包括搅拌辊。 当消耗显影剂时,两个部分被分离,并且只有第二部分与搅拌辊被丢弃以便更换。 为了有效地收集用过的显影剂,可以将棒状磁体插入到形成在搅拌辊的轴内部的室中以利用其磁力,或者可以提供刮刀以刮除剩余的显影剂 到显影辊。 在蛤壳式复印机的主体的顶部相对于其基部旋转地打开的情况下,当打印复印机进行更换时,显影装置变得倾斜。 用于摇动罐的装置可以有效地使剩余的显影剂移动到装置的下部以便于收集。

    • An electrophotographic copying machine including a unit consisting of a photoreceptor and a developing device. The unit can be pulled out of or into the copying machine. The developing device has a developer outlet provided at its bottom, and first and second grooves. A developer funnel can be coupled to the first groove to receive the old developer from the developing device. The first groove is also provided for guiding a lid closing the developer outlet. The funnel can also be coupled to the second groove to supply the new developer. In a specific form, the developing device can be shifted from a position close to the photoreceptor to a position separate from the same. The developing device can also be moved with a quadric link chain pivotally supported on the frame of the unit of the photoreceptor and the developing device. Positioning members are provided in the frame for positioning the developing device in both positions.
