    摘要： A roll has a base material layer, a front surface layer, and stress relaxation layer. The base material layer is made of low hardness rubber material and provided on an outer circumference of a metal core. The stress relaxation layer is provided on the base material layer and made of material which is at least higher in hardness than the base material layer and larger in stretch than the front surface layer. The front surface layer is made of resin material and provided on the stress relaxation layer. The stress relaxation layer is made of rubber material containing self-crosslinking resin. The stress relaxation layer has a thickness in a range of from 5 to 50 &mgr;m, and stress not lower than 5 MPa at 10% stretch.
