Provided is a cleaning member, comprising an elastic member that includes polyurethane, wherein: when tan δ of a test piece sampled from the elastic member is measured in the temperature range of −20° C. to +60° C., the peak temperature of a peak indicating the maximum value of tan δ is at 15.0° C. or below; the maximum value of tan δ is 0.20 to 0.55; tan δ at a temperature of 55° C. is 0.13 or larger; and where the detected quantity of all ions obtained when the test piece is heated at a rate of temperature increase of 10° C./second to 1000° C. using a direct-sampling mass spectrometer is M1 and the integrated intensity of a peak in a derived ion thermogram that corresponds to a range of m/z values originating in multifunctional isocyanate with at least three isocyanate groups is M2, M2/M1 is at least 0.001.
