Abstract
A photoconductive surface, a carbon loaded, elastomeric roller having two levels of impedance under two distinct loading conditions situated adjacent the photoconductive surface, and a device for generating two different loading conditions on the roller to thereby produce the two levels of impedance, wherein when the roller is subjected to the lower level of loading the roller is operable for charging the photoconductive surface and when the roller is subjected to the higher level of loading the roller is operable for transferring a developed image from the photoconductive surface to a receiver sheet.
