    • In a developing device including a developer tank and a developing roller, an internal space of the developer tank is partitioned by a partition into a first conveying path, a second conveying path, a first communication path, and a second communication path. A first developer conveying section that conveys the developer in the developer tank in a first conveying direction X is disposed in the first conveying path. A second developer conveying section that conveys the developer in the developer tank in a second conveying direction Y is disposed in the second conveying path. The first developer conveying section includes a first spiral blade, and a rotation tube.
    • 在包括显影剂罐和显影辊的显影装置中,显影剂罐的内部空间被隔板分隔成第一输送路径,第二输送路径,第一通信路径和第二通信路径。 在第一传送路径中设置有将第一传送方向X上的显影剂槽中的显影剂输送的第一显影剂输送部。 在第二输送路径中配置有将显影剂槽中的显影剂沿第二输送方向Y输送的第二显影剂输送部。 第一显影剂输送部分包括第一螺旋叶片和旋转管。

    • A developing device comprising: a developer tank housing a developer including a toner and a carrier; a toner replenishment port; a developing roller; a first developer conveying path and a second developer conveying path; a conducting plate for peeling a recovery developer on a surface of the developing roller after the toner is supplied to a photosensitive drum from the surface of the developing roller so as to guide the recovery developer to the first developer conveying path; and first and second developer conveying members arranged on the first and second developer conveying paths, wherein the first developer conveying member has a cylindrical hollow rotating shaft with opened both ends that is rotatably provided to the first developer conveying path, and divides the first developer conveying path into an external first developer conveying path and an internal first developer conveying path, an external spiral blade fixed to an outer periphery of the hollow rotating shaft, and an internal spiral blade fixed to an inner periphery of the hollow rotating shaft, a direction where the developer is conveyed by the external spiral blade is the same as a direction where the developer is conveyed by the second developer conveying member and is opposite to a direction where the developer is conveyed by the internal spiral blade.
    • 一种显影装置,包括:容纳包含调色剂和载体的显影剂的显影剂罐; 调色剂补充口; 显影辊; 第一显影剂输送路径和第二显影剂输送路径; 将调色剂从显影辊的表面供给到感光鼓之后,将显影辊的表面上的回收显影剂剥离的引导板,以将回收显影剂引导到第一显影剂输送路径; 以及布置在第一和第二显影剂传送路径上的第一和第二显影剂传送构件,其中第一显影剂传送构件具有圆柱形空心旋转轴,其两端敞开,可旋转地设置在第一显影剂输送路径上,并且将第一显影剂输送 进入外部第一显影剂输送路径和内部第一显影剂输送路径的路径,固定到中空旋转轴的外周的外部螺旋叶片和固定到中空旋转轴的内周的内部螺旋叶片, 由外部螺旋叶片输送的显影剂与显影剂被第二显影剂输送构件输送的方向相同,并且与由内部螺旋叶片传送显影剂的方向相反。

    • Conventionally, the magnetic field generator was arranged perpendicularly to the axis of the electron beam. The magnetic field generator of this invention is arranged so as to be inclined relative to the plane perpendicular to the axis of the electron beam. Specifically, the magnetic field generator is arranged so as to be inclined relative to the plane perpendicular to the axis of the electron beam within the range in the cathode side from the focused and deflected electron beam. Inclination up to the anode side opposite to the cathode side will lead to a possibility of increasing the reduced X-ray source diameter. Thus, arranging the magnetic field generator so as to be inclined within the range in the cathode side from the electron beam may reduce the X-ray source diameter.
    • 通常,磁场发生器垂直于电子束的轴线布置。 本发明的磁场发生器被布置成相对于垂直于电子束轴的平面倾斜。 具体地说,磁场发生器被布置为相对于垂直于电子束轴线的平面在从聚焦偏转电子束的阴极侧范围内倾斜。 直到与阴极侧相反的阳极侧的倾斜将导致增加X射线源直径减小的可能性。 因此,将磁场发生器设置成在电子束的阴极侧的范围内倾斜,可能降低X射线源直径。
