Abstract
The presently disclosed embodiments are directed to charging devices which produce a negative corona. The present embodiments pertain to the use of a positive charging device, such as a scorotron, after the erase lamp and before negative charging station in the xerographic cyclic to mitigate the undesirable changes in charge transport layer electrical properties that result from exposure to corona while negatively charging the photoreceptor during latent image formation.
