Abstract
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.
