Abstract

A method for reducing contamination of a corona charger in an electrophotographic process wherein the corona charger imparts a charge to a photoconductor film passed by the corona charger, by identifying contaminated air flow streams and determining the direction of flow of the contaminated air flow stream flowing past or into the corona charger and positioning at least one plate to divert the contaminated air flow streams away from the corona charger.
