PROBLEM TO BE SOLVED: To provide a semiconductive resin composition which contains a thermoplastic resin, a conductive resin, and conductive inorganic particles, and has required semiconductivity, has small voltage dependency (electrical characteristics) of a resistance value, has a small difference between electrical characteristics in a belt surface, and can secure compatibility of a quality problem (mechanical characteristics) caused by belt elongation or the like and belt surface property (glossiness), when being used as an intermediate transfer belt.SOLUTION: A semiconductive resin composition contains a non-conductive resin, a conductive resin, and conductive inorganic particles. The conductive particles are conductive glass, and has a content of 0.01 wt.% to 5.0 wt.%.SELECTED DRAWING: Figure 1 【課題】熱可塑性樹脂と導電性樹脂と導電性無機粒子を含有し、中間転写ベルトとして用いたときには、求められる半導電性を持ち、抵抗値の電圧依存性（電気特性）が小さく、ベルト面内の電気特性の差が少なく、ベルト伸びなどによる品質課題（機械特性）、ベルト表面性（光沢度）、の両立性が確保できる半導電性樹脂組成物を提供すること。【解決手段】非導電性樹脂と導電性樹脂と導電性無機粒子を含有し、該導電性粒子が導電性ガラスであり、その含有量が０．０１ｗｔ％〜５．０ｗｔ％であることを特徴とする半導電性樹脂組成物。【選択図】図１
