摘要： PROBLEM TO BE SOLVED: To stably hold the coefficient of friction of the surface of a roller for a long period by providing a cylindrical buffer material, an elastically deformable and cylindrical metallic surface material coating the outer peripheral surface of the buffer material and hard particulate applied on the outer peripheral surface of the metallic surface material. SOLUTION: The paper carrier roller is constituted of a thick and cylindrical buffer material 1, a thin and cylindrical surface material 2 coating the outer periphery of the buffer material 1 and hard particulate 3 applied evenly on the whole of the outer periphery of the surface material 2. The buffer material 1 is formed by a material which can be easily elastically deformed by pre-load loaded on this kind of paper carrier roller, that is, a rubber material and foamed resin material, for instance. The surface material 2 is formed by a metallic material, that is, stainless steel rich in corrosion resistance, for instance. The thickness of the surface material 2 is made to thin so as to be elastically deformable. As the hard particulate 3, ceramic particulate having a sharp angular part and a particle diameter of about 10 to 150 μm, for instance, is used.
