Provided is a rubber composition which can suppress coloration of the surface of a rubber article by having better weather resistance than conventional rubber compositions. This rubber composition is characterized by being formed by mixing at least one bisanilino compound represented by expression (I) [in the expression, R1 and R2 independently represent a hydrogen atom or an alkyl group of 1-6 carbon atoms; m and n represent the integers 0 or 1; A1 represents an alkylene group of 1-7 carbon atoms; A2 represents an alkylene group of 1-8 carbon atoms; X1 represents an oxygen atom, a sulfur atom or an -NR3-group; X2 represents an oxygen atom, a sulfur atom or an -NR4-group; here, R3 and R4 are a hydrogen atom or an alkyl group of 1-4 carbon atoms, or R3 and R4 optionally combine to form an alkylene group of 1-4 carbon atoms] with at least one rubber component selected from natural rubbers and diene-based synthetic rubbers. 本公开提供了包含选自天然橡胶和二烯类合成橡胶中的至少种橡胶组分、以及相对于所述橡胶组分进行混合的如下式(I)表示的双苯胺基化合物中的至少种的橡胶组合物，其中，在式(I)中，R和R
