To provide a cleaning member and an elastic member capable of preventing a deterioration in wiping performance even when raised in temperature due to use in a high-temperature environment or use over a long period.SOLUTION: A cleaning member comprises an elastic member including polyurethane. In the cleaning member, when tanδ of a sample taken from the elastic member is measured in a temperature range of -20°C to +60°C, a peak temperature of a peak indicating the maximum value of tanδ is 15.0°C or lower, the maximum value of tanδ is 0.20 or more and 0.55 or less, and tanδ at a temperature of 55°C is 0.13 or more. In addition, when a detection quantity of all ions obtained upon heating the sample at a rate of temperature increase of 10°C/second to 1,000°C by using a mass spectrometer of a direct sample introduction system is M1, and when an integrated intensity of a peak in an extracted ion thermogram corresponding to the range of m/z values originating in polyfunctional isocyanate with three or more isocyanate groups is M2, M2/M1 is 0.001 or more.SELECTED DRAWING: Figure 1

【課題】高温環境での使用や、長時間に亘る使用により、昇温した場合にも払拭性能の低下を防止し得る清掃部材及び弾性部材。【解決手段】ポリウレタンを含む弾性部材を備えた清掃部材であって、該弾性部材からサンプリングした試料のｔａｎδを温度－２０℃～＋６０℃の範囲で測定したとき、ｔａｎδの最大値を示すピークのピーク温度が、１５．０℃以下に存在し、ｔａｎδの最大値が、０．２０以上０．５５以下であり、温度５５℃におけるｔａｎδが、０．１３以上であり、かつ、該試料を直接試料導入方式の質量分析計を用いて、昇温速度１０℃／秒で１０００℃まで加熱したときに得られる全てのイオンの検出量をＭ１とし、イソシアネート基を３個以上有する多官能イソシアネートに由来するｍ／ｚ値の範囲に対応する抽出イオンサーモグラムのピークの積分強度をＭ２としたとき、Ｍ２／Ｍ１が０．００１以上である。【選択図】図１
