PROBLEM TO BE SOLVED: To provide a chromium content of 10 which is stable in adhesion to a rubber material. %, Which significantly reduces the generation of rust in steel materials, and provides an environmentally favorable and inexpensive roller. SOLUTION: In a roller having a resin coating layer formed through a heat effect process, a metal core body is not plated with a steel material having a chromium content of 10% or less, and a roller is formed. During the process, at least the outer periphery of the resin coating layer outside the coating range is subjected to a rust prevention process, and the rust prevention process is performed in the adhesive application step. It is characterized in that the treatment is performed at the time of heat curing of the roller covering material. |
