Abstract
Embodiments of a wet contact charging method and apparatus for electrophotography charging stations are shown and described. Each embodiment includes placing a charging member, having a charge bias, against an electrophotography charge-receiving member, and placing a liquid between the charging member and charge-receiving member. Preferably, a charging roller is rotated through a liquid-filled container and the wet roller carries liquid into the nip between the roller and a photoconductor. This wet contact charging results in stable, uniform charging without photoconductor release property degradation.
