METHOD FOR MANUFACTURING RUBBER ROLLER FOR ELECTRIFICATION MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method to easily and efficiently manufacture a rubber roller for an electrification member having a smooth surface layer with uniform film thickness and having low hardness. SOLUTION: In the method for manufacturing a rubber roller for an electrification member having at least two layers of semiconductive rubber layers on the peripheral surface of a conductive axial body, a semiconductive foaming rubber material not vulcanized nor foamed is disposed on the peripheral surface of the conductive axial body, and further a latex type semiconductive non- foaming rubber material is disposed as a single layer or a plurality of layers on the peripheral surface of the semiconductive foaming rubber material. Then the axial body is mounted in the molding cavity of a cylindrical die and subjected to the vulcanization and foaming process to form a semiconductive foamed rubber layer and a semiconductive non-foamed rubber layer on the peripheral surface of the conductive axial body into one body.
