摘要： A developing apparatus for developing a latent image on a surface of a photosensitive body by forming a toner cloud in a developing region through electrode wire, in which movably supporting units for supporting electrode supporting unit movably between operative positions and inoperative positions are provided so that the electrode wire supported by the electrode supporting units can be kept in an operative position near to a surface of a developing roll when the electrode supporting units are in their operative positions and, on the other hand, the electrode wire can be kept in an inoperative position far from the surface of the developing roll when the electrode supporting units are in their inoperative positions. Thereby, foreign matters trapped in the electrode wire or accumulated on the electrode wire can be removed easily.
摘要翻译：一种显影装置，用于通过在显影区域中通过电极线形成调色剂云来显影感光体表面上的潜像，其中可动支撑单元用于在可操作位置和不工作位置之间可移动地支撑电极支撑单元，当电极支撑单元处于其操作位置时，由电极支撑单元支撑的电极线可以保持在显影辊表面附近的操作位置，另一方面，电极线可以保持在不工作位置当电极支撑单元处于其不工作位置时远离显影辊的表面。由此，能够容易地除去捕获在电极线中或积聚在电极线上的异物。
