Abstract
Provided are a polyimide tube that can be produced at a low cost and has good durability and a good offset property, a method for producing the polyimide tube, and a fixing belt which includes the polyimide tube as a base and which has good durability and a good offset property. Provided are a polyimide tube including a base resin containing a polyimide resin having good rigidity and a soft polyimide resin having good flexibility in a mass ratio of 30:70 to 70:30, 20% to 50% by volume of graphite, 3% by volume or more of a highly conductive carbon black particle, and 0.5% by volume or more of a carbon nanotube relative to the volume of the base resin, a method for producing the polyimide tube, and a fixing belt including the polyimide tube as a base.
