PROBLEM TO BE SOLVED: To provide a conductive member that includes a surface layer capable of sufficiently suppressing bleeding of an ion conductive agent.SOLUTION: A conductive member R is used for an image forming apparatus of an electrophotographic system. The conductive member R includes a surface layer 1. The surface layer 1 includes a crosslinked body having a portion derived from (A), portion derived from (B), and portion derived from (C) in its molecular structure. In the surface layer 1, (A) is an ion conductive agent comprising a salt of a cation having an OH group and an anion; (B) is polyisocyanate; (C) is a silane coupling agent.SELECTED DRAWING: Figure 1 【課題】イオン導電剤のブリードを十分に抑制することができる表層を有する導電性部材を提供する。【解決手段】導電性部材Ｒは、電子写真方式の画像形成装置に用いられる。導電性部材Ｒは、表層１を有している。表層１は、（Ａ）に由来する部位と（Ｂ）に由来する部位と（Ｃ）に由来する部位とを分子構造中に含む架橋体を有している。但し、（Ａ）は、ＯＨ基を有するカチオンとアニオンとの塩からなるイオン導電剤、（Ｂ）は、ポリイソシアネート、（Ｃ）は、シランカップリング剤である。【選択図】図１
