A rubber composition in which a transfer roller with lower resistance than in the related art is able to be formed without increasing a blending ratio of epichlorohydrin rubber, a transfer roller including the rubber composition, and an image forming apparatus having the transfer roller incorporated therein are provided. The rubber composition is obtained by blending rubbers including at least oneof NBR, SBR, and BR and epichlorohydrin rubber with a crosslinking component, a foaming component, and 3 to 50 parts by mass aluminum silicate with respect to 100 parts by mass of the total amount ofrubbers. A transfer roller (1) includes a roller main body (2) formed by extrusion-molding the rubber composition in a tubular shape and foaming and crosslinking the rubber composition. The image forming apparatus includes the transfer roller (1) incorporated therein. 本发明提供一种可不使表氯醇橡胶的调配比例增加而形成比目前低电阻化的转印辊的橡胶组合物、包含所述橡胶组合物的转印辊、以及安装有所述转印辊的图像形成装置。橡胶组合物是将相对于橡胶的总量100质量份而为3质量份～50质量份的硅酸铝与交联成分、发泡成分一起调配于包含NBR、SBR及BR中的至少一种与表氯醇橡胶的橡胶中。
