POLYANALINE AND CARBON BLACK FILLED POLYIMIDE INTERMEDIATE TRANSFER COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an intermediate transfer member capable of ensuring resistance in a desired range according to a printing step. SOLUTION: In a toner transfer system for a xerographic copier in which charged toner particles are transferred once to the intermediate transfer member and then transferred to a copying sheet or the like, the intermediate transfer member is composed of a polyimide substrate 40 in which a polyanaline electrically conductive filler and a carbon black electrically conductive filler have been dispersed and an outer layer 41. By this structure, controllable resistivity can be imparted to the intermediate transfer member and a desired electric field for transfer corresponding to the speed of a printing step can be provided in such a range as not to cause dielectric breakdown in the transfer of a toner.
