Abstract
A conductive member includes a conductive supporter, an electric resistance adjusting layer formed on the conductive supporter and gap retaining members which are of a different material from that of the electric resistance adjusting layer and are disposed respectively at both ends of the electric resistance adjusting layer for contacting an image carrier so as to maintain a predetermined gap between the electric resistance adjusting layer and the image carrier, wherein the electric resistance adjusting layer is made from a resin composition containing a thermoplastic resin containing an ether group, an organic phosphonium salt and a fluorine-containing organic anion salt.
