ABSTRACT:
A fixing roller for thermally fixing an unfixed toner image is comprised of a core cylinder and a fluororesin tube fused on the core cylinder. The core cylinder is provided on its periphery with a minute groove means. On fusing the fluororesin tube on the core cylinder, the minute groove means gives to the surface of the fluororesin tube convexities or concavities extending in parallel in the peripheral direction of the fixing roller.
