PROBLEM TO BE SOLVED: To provide a method for performing surface treatment of a rubber member, the method realizing production of a rubber member which has low hardness and thus can respond to deformation and which does not cause staining of an OPC and the like and leakage. SOLUTION: The method for performing surface treatment of the rubber member comprises impregnating a rubber member with a first surface-treatment liquid containing an isocyanate component and an organic solvent to form a first impregnation layer, and sequentially treating the 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.
