にこのような膜浮きをしばしば生じていた。(Problem to be Solved by the Invention) However, the adhesive force between the PTFE layer of such a roller and the rubber layer of MW is not so strong because the adhesive force is due to a mechanical so-called anchor effect. However, there was a problem in that the PTFE layer lifted during use, impairing the durability of the roller. Furthermore, since this adhesive force is particularly small near room temperature, such film lifting often occurs even during the handling stage before use.
