PROBLEM TO BE SOLVED: To provide a conductive member having small fluctuation of electric resistance due to processing conditions and uniform electric resistance.SOLUTION: There is provided a conductive member having a conductive support body and a conductive elastic layer. The elastic layer is a cured product of a mixture containing carbon black and binder polymer. In the carbon black, an average primary particle diameter is 20 nm or more and 30 nm or less, a DBP oil absorption amount is 40 ml/100 g or more and 70 ml/100 g or less, the total amount of CO and COgenerated by heated gas generation analysis is 0.30 mass% or more and 0.80 mass% or less on the carbon black standard, and the amount of SOgenerated by the heated gas generation analysis is 0.05 mass% or more on the carbon black standard. |
