Abstract
A method and system for producing rolls for electrophotography are provided. The rolls can be rotated and shifted laterally during an oxidative baking process to produce finished rolls having improved electrical and printing characteristics. The oxidation of the rolls may be controlled to provide a corresponding increase in surface electrical resistance to within plus or minus 25 microns of a selected roll thickness.
