Claim:
1. A conductive roller comprising a shaft, at least one elastic layer formed on the outer periphery of the shaft and a surface layer formed on the outer peripheral surface of the elastic layer, wherein the elastic layer is formed by using a coating for elastic layers containing a liquid absorbing agent, and the surface layer is formed by using a coating for surface layers, wherein both of the coating for elastic layers and the coating for surface layers contain a water-based coating which is an emulsion or dispersion, and the water-based coating used in the elastic layer is a water-based acrylic resin having acrylonitrile and n-butyl acrylate as essential components and optionally having other monomers, and the monomer ratio of n-butyl acrylate and acrylonitrile is in a range of 1 to 25:99 to 75 based on molar ratio.
