SEMIELECTROCONDUCTIVE POLYIMIDE RESIN BELT AND PROCESS FOR PRODUCING SEMIELECTROCONDUCTIVE POLYIMIDE RESIN BELT

摘要

This invention provides a semielectroconductive polyimide resin belt, particularly an intermediate transfer belt formed of the semielectroconductive polyimide resin belt, which can simultaneously realize electric characteristics high enough, for example, to cause accurate transfer in a color image forming device and to stably produce high-quality transferred images for a long period of time, and excellent physical properties, for example, low susceptibility to a deterioration in planarity derived from a change in plasticity by a load applied in the widthwise direction of the belt, excellent durability, and stable use even when it is travelled for a long period of time. The semielectroconductive polyimide resin belt comprises a carbon black and a polyimide resin. The semielectroconductive polyimide resin belt is characterized in that the polyimide resin is produced by imidating terphenyl-3, 3', 4, 4'-tetracarboxylic acid dianhydride with an aromatic diamine and contains not less than 50% by mole of an aromatic diamine of which the number of aromatic rings based on the total amount of the aromatic diamine is three and/or four.
