ABSTRACT:
The present invention relates to electrically conductive polyimide films having dispersed in them electrically conductive polymer particles having an average particle size from 0.5 to 5.0 microns. These films are suitable as image transfer belts in high-speed color copying machines and possess a surface smoothness, Ra factor (microns), between 0.5 and 1.5 and a gloss factor between 70 and 120.
