Zusammenfassung:PROBLEM TO BE SOLVED: To provide a member for an electrophotographic device that can maintain low friction on a surface of a surface layer and significantly improve toner chargeability compared with a prior art member.SOLUTION: A member R for an electrophotographic device comprises a surface layer 1. The surface layer 1 contains a matrix polymer and a surface modification agent. The matrix polymer contains a polymer of polyisocyanate and a hydrophobic organic compound containing one or more functional groups reacting with an isocyanate group in polyisocyanate. The surface modification agent is formed of a polymer containing an amino group and a silicone group in a molecule.SELECTED DRAWING: Figure 5 【課題】表層表面の低摩擦性を維持しつつ、従来に比べ、トナー荷電性を大幅に向上させることが可能な電子写真機器用部材を提供する。【解決手段】電子写真機器用部材Ｒは、表層１を有している。表層１は、マトリックスポリマーと、表面改質剤とを有している。マトリックスポリマーは、ポリイソシアネートと、ポリイソシアネートのイソシアネート基と反応する官能基を１つ以上含む疎水性有機化合物との重合体を含んでいる。表面改質剤は、分子内にアミノ基およびシリコーン基を含むポリマーより構成されている。【選択図】図５
