摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for an elastic roll to prevent a situation that rubber is stuck and left as it is on a removal mark formed when removing both ends of a cross-linked rubber layer after forming the cross-linked rubber layer by using hydrosilylated cross-linked rubber composition as material on the outer periphery of a shaft body whose surface is electroless nickel plated. SOLUTION: By using a plating liquid set so that the concentration of a stabilizer composed of sulfur compound may be under 0.01 mg/liter, the surface of the shaft body is electroless nickel plated. After a rubber layer composed of the hydrosilylated cross-linked rubber composition is formed in tight-contact with the outer periphery of the shaft body, it is cross-linked to form the cross-linked rubber layer. Then, both ends in the shaft direction of the cross-linked rubber layer are cut off. COPYRIGHT: (C)2008,JPO&INPIT
