Provided are a fluororesin tube that has substantially no scratches formed during manufacturing, and a rotary member for a fixing device, the rotary member obtained by using the fluororesin tube. The fluororesin tube is a heat-shrinkable fluororesin tube that covers a rotary member for a fixing device, such as a fixing roller or a pressure roller, to form an outermost layer of the rotary member, wherein a maximum depth of a linear scratch on a surface of the fluororesin tube is 0.8 μm or less. In one embodiment, the length of the linear scratch is 1 mm or less, and the thickness of the fluororesin tube is 100 μm or less.
