To provide a tubular body for fixing in which wear resistance of a releasing layer is excellent to high speed paper carriage over 20 ppm, offset is hardly generated over a long period of time and releasing property is excellent to anchored toner.

The tubular body for fixing having a tubular inner layer made of a heat resistant resin and an outer layer with releasing property disposed at an outer peripheral part thereof, is distinguished by that the outer layer with releasing property consists essentially of a fluorine resin and further contains a thermosetting resin.
