Polyimide precursor solution, transfer/fixing member and process for producing polyimide seamless belt

摘要

The object of the present invention is to provide a polyimide precursor solution having a good coating workability. Another object of the present invention is to provide transfer and fixing parts such as a polyimide seamless belt and the like produced from said polyimide precursor solution. Said polyimide precursor solution is produced by dissolving said polyimide precursor which is a homopolymer or copolymer of a polyamide acid in a solvent mixture of one or more kind(s) of solvent having a lower boiling point under 100° C., and one or more kind(s) of solvent having a higher boiling point of 100° C. or more, wherein said higher boiling point solvent (s) is (are) contained in said solvent mixture in an amount of 5 to 55% by weight.
