PROBLEM TO BE SOLVED: To provide a low deformation coated roll in which wrinkles or cracks in the surface coating film can be suppressed or prevented. SOLUTION: A roll-type product is obtained by coating the outer surface of a conductive axial body with an elastic layer and coating the outer surface of the elastic layer with a coating film of urethane or the like. The product is controlled in such a manner that the curvature α0 of the diameter of the roll-type product at normal temperature and normal humidity and the curvature α1 of the diameter of the product just after heat treatment satisfy the relation of 0<α0 -α1 <0.01. |
