摘要： An electrostatic charging device is provided according to which an edged electrode plate can be inserted into and removed from the charging device easily merely by sliding the edged electrode member and cleaning of the electrode edges formed on the edged electrode plate can be cleaned easily. A discharging electrode assembly having a number of tooth-like electrode edges disposed in array is slidable along a guide groove formed in a discharge stabilizing shielding case of an electrostatic charging device. The electrode edges are arranged above a control grid when charging a photosensitive OPC. During maintenance, the discharging electrode assembly is moved sliding along the guide groove by means of an insulating attachment which is then engaged with the edged electrode plate. During this movement, the edged electrode plate is sandwiched by a pair of rotatable rollers which are then driven to rotate by the sliding movement, so that electrode edges attached with carbon particles due to corona discharging can be cleaned. Thus, the discharging electrode assembly can be inserted and removed easily with the electrode edges thereof being cleaned simultaneously without removing a charger case or the control grid from the device proper.
摘要翻译：提供了一种静电充电装置，根据该静电充电装置，边缘电极板可以容易地仅通过滑动边缘电极部件而插入和移出充电装置，并且可以容易地清洁形成在边缘电极板上的电极边缘。具有排列成阵列的多个齿状电极边缘的放电电极组件可以沿着形成在静电充电装置的放电稳定屏蔽壳体中的引导槽滑动。当对光敏OPC充电时，电极边缘布置在控制栅格的上方。在维护期间，放电电极组件通过绝缘附件沿引导槽滑动，然后与边缘电极板接合。在该移动期间，边缘电极板被一对可旋转的辊夹持，然后通过滑动运动来驱动旋转辊，从而可以清洁由于电晕放电而附着碳颗粒的电极边缘。因此，可以容易地插入和移除放电电极组件，同时清洁电极边缘，而不从设备本身移除充电器壳体或控制栅格。
