ABSTRACT:
The invention provides a charging roller for electrically charging a photoconductor by placing the roller in contact with the photoconductor and applying voltage between them. The roller has an elastic shaft and an outermost layer of less than 30 .mu.m thick containing an aqueous fluorocarbon resin. The charging roller is effective for providing a constant supply of electric charge to the photoconductor and preventing residual toner from depositing onto the roller.
