Moreover, even if the polyolefin resin film or the film covered with an inflation film is used, it is difficult to say that the center part of the roll attached to the shaft is made of rubber, so that the durability is not sufficient. Was simply put on,
Or because it is only covered on the surface of the rubber roll due to heat shrinkage, there is a risk that the polyolefin film, etc. may peel off from the surface of the rubber roll during long-term use, and it is difficult to achieve stable paper feeding over the long term. A resin base having a shaft insertion hole; a thermoplastic elastomer intermediate elastic layer formed on the outer peripheral surface of the base; and an ultrahigh molecular weight polyethylene outer surface layer formed on the outer peripheral surface of the intermediate elastic layer. Has been proposed (for example, see Patent Document 2).
