    • A coronode charging device includes a support member, a filament, an adjustment mechanism and a voltage source. The lament is disposed along the support member in a configuration that creates a plurality of active regions and a plurality of inactive regions of the filament. The active regions are simultaneously positionable adjacent the photoreceptor. The inactive regions may be farther from the photoreceptor than the active regions. The adjustment mechanism moves the filament such that portions of the filament that correspond to the active regions are moved to positions that correspond to the inactive regions, and some portions of the filament that were in the inactive regions are moved to positions that correspond to the active regions. This operations extends the life of the coronode charging device.
    • 冠状体充电装置包括支撑构件,灯丝,调节机构和电压源。 该纱线沿着支撑构件设置成以形成多个有源区域和多个无效区域的构造。 有源区域可以与感光体相邻定位。 非活性区域可以比活性区域远离感光体。 调节机构使细丝移动使得与活性区域相对应的细丝部分移动到与非活性区域对应的位置,并且处于非活性区域的丝线的一些部分被移动到与活性区域对应的位置 地区。 该操作延长了冠状体充电装置的使用寿命。
