Abstract
A conductive member includes, a conductive supporting body, an electric resistance-adjusting layer formed in the conductive supporting body, and a space holding member which is formed on each end of the electric resistance-adjusting layer and has a material different from a material of the electric resistance-adjusting layer, the space holding member constantly maintaining a space between an image carrier and the electric resistance-adjusting layer, and the electric resistance-adjusting layer including a resin composition having a thermoplastic resin (A) containing at least an ether group, a fibrous polymer (B), which do not melt in (A) and has an aromatic skeleton in a molecule, and an electrolyte salt (C).
