Abstract
The method for performing surface treatment of a rubber member includes impregnating a rubber member with a first surface-treatment liquid containing an isocyanate component and an organic solvent, to thereby form a first impregnation layer, and sequentially treating a surface of the rubber member, without exposure to air, with a second surface-treatment liquid for partially removing the isocyanate component present in the first impregnation layer.
