<p>PROBLEM TO BE SOLVED: To provide an electrophotographic member that can achieve both of suppression of increase in hardness and improvement in wear resistance of a rubber elastic body surface using acrylonitrile butadiene rubber.SOLUTION: An electrophotographic member 1 has a rubber elastic body 3 having a surface exposed to the outside. The rubber elastic body 3 is a thermally cured product of a rubber composition comprising: a matrix polymer including acrylonitrile butadiene rubber having an acrylonitrile content of 40 mass% or less; and a polyvalent isocyanate having two or more isocyanate groups in the molecule. The rubber composition has an isocyanate group content of 0.4 mass% to 10 mass%.</p> |
