A paper-feeding roller ( 3 ) including a core ( 2 ) and a rubber roll ( 1 ) mounted on a peripheral surface of the core ( 2 ). The rubber roll ( 1 ) has a three-layer construction composed of an inner layer ( 11 ), an intermediate layer ( 12 ), and an outer layer ( 13 ). The inner layer ( 11 ), the intermediate layer ( 12 ), and the outer layer ( 13 ) are a non-foamed layer respectively. The JIS-A hardness of the inner layer ( 11 ) is set to not more than 10 degrees. The JIS-A hardness of the outer layer ( 13 ) is set to a range of 25 to 60 degrees.
