US09031472B2 Developing device with a developer conveying member having paddles connecting spiral blades at one circumferential position and image forming apparatus with such a developing device 有权
具有显影剂输送构件的显影装置，该显影剂输送构件具有在一个周向位置处连接螺旋叶片的刮板和具有这种显影装置的图像形成装置

Developing device with a developer conveying member having paddles connecting spiral blades at one circumferential position and image forming apparatus with such a developing device
Abstract:
A developing device includes a housing containing a developer, a developer carrier, a developer conveying path, a developer conveying member, and a plurality of paddle members. The developer conveying path includes a first conveying path and a second conveying path. The developer conveying member is disposed in the second conveying path and includes a rotating shaft and spiral blades formed around the rotating shaft. The developer conveying member is rotationally driven to convey the developer in the second direction and feeds the developer to the developer carrier. The plurality of paddle members project in a radial direction from the rotating shaft of the developer conveying member at one circumferential position on the rotating shaft. The plurality of paddle members is contiguously arranged in the axial direction of the rotating shaft to connect the spiral blades adjacent to each other in the axial direction.
Abstract(Chinese):

显影装置包括容纳显影剂，显影剂载体，显影剂输送路径，显影剂输送构件和多个桨状构件的壳体。 显影剂输送路径包括第一输送路径和第二输送路径。 显影剂输送构件设置在第二输送路径中，并且包括旋转轴和围绕旋转轴形成的螺旋叶片。 旋转地驱动显影剂输送构件以沿第二方向输送显影剂，并将显影剂供给显影剂载体。 多个叶片构件在旋转轴的一个圆周位置处从显影剂传送构件的旋转轴在径向方向上突出。 多个叶片构件沿旋转轴的轴向连续地布置，以沿着轴向相互连接的螺旋叶片。
