The present invention provides a conductive roller which has excellent resilience in response to deformation and exhibits small variation in electrical resistance. The conductive roller has a metallic core, a conductive elastic layer formed on the outer surface of the core to which layer conductivity has been imparted by carbon black, and a surface-treated layer formed through impregnating a surface of the conductive elastic layer with a surface-treatment liquid, wherein the difference DeltaHs (Hs<SUB>1</SUB>-Hs<SUB>2</SUB>) between micro-hardness Hs<SUB>1 </SUB>of a surface of the conductive roller and micro-hardness Hs<SUB>2 </SUB>of the conductive elastic layer after removal of the surface-treated layer, the hardness being determined by means of a micro-hardness tester, is 5% or less of the micro-hardness Hs<SUB>2</SUB>.
