Abstract
Provided are a polyimide tube including a polyimide resin composition, wherein the polyimide resin composition contains a polyimide resin in which an acicular highly thermally conductive filler such as carbon nanotubes is dispersed in 15 volume percent or more relative to the total volume of the composition; the acicular highly thermally conductive filler has an orientation of 1.3 or more, the orientation being represented by the modulus of elasticity of the polyimide resin composition in the circumferential direction/the modulus of elasticity of the polyimide resin composition in the axial direction; and the polyimide tube has high thermal conductivity, is excellent in terms of mechanical strength and indentation strength, and provides a high fixing property and an excellent offsetting property; a process for producing such a tube; and a fixing belt including such a tube serving as a base member.
