用于将带电显影剂供应到预期装置的显影剂供应装置和具有该显影剂供应装置的图像形成装置

Developer supply device for supplying charged development agent to intended device and image forming apparatus having the same
Abstract:
A developer supply device includes a developer-carrying body having a developer-carrying surface that faces an intended device in a first position and moves in a moving direction, a first transfer board that faces the developer-carrying surface in a second position upstream relative to the first position in the moving direction and transfers the developer to the second position in a direction opposite to the moving direction in the second position, an electrification member facing the developer-carrying surface in a third position downstream relative to the second position and upstream relative to the first position in the moving direction, and a second transfer board that faces the developer-carrying surface in a fourth position downstream relative to the first position and upstream relative to the second position in the moving direction and transfers the developer to a developer storage section in a direction identical to the moving direction in the fourth position.
Abstract(Chinese):

显影剂供应装置包括具有显影剂承载表面的显影剂承载体，所述显影剂承载表面在第一位置处面向预期装置并沿移动方向移动;第一转印板，其相对于 在移动方向上的第一位置，并将显影剂在与第二位置的移动方向相反的方向上移动到第二位置，在第三位置中相对于第二位置和上游相对的第三位置面对显影剂承载表面的带电构件 移动方向上的第一位置，以及第二转印板，其在相对于第一位置下游的第四位置处相对于显影剂承载表面相对于沿着移动方向的第二位置的上游，并将显影剂转移到显影剂储存器 在与第四位置的移动方向相同的方向上。
