| titleOfInvention | Conductive roller |
| abstract | An object of the present invention is to provide a conductive roller having excellent potential stability even in long-term use. Further, an image forming apparatus having the conductive roller is provided. A shaft and a plurality of layers formed on the outer periphery of the shaft, wherein the plurality of layers formed on the outer periphery of the shaft have at least a base layer, a lower layer, and a surface layer in this order from the shaft side. The base layer contains a polyurethane foam and carbon black, the lower layer contains a resin component, an ionic conductive agent, and carbon black, and the content of the ionic conductive agent is at least 8 parts by mass and at most 12 parts by mass with respect to 100 parts by mass of the resin component. and a part or less, the surface layer is a urethane resin, and containing carbon black, the average primary particle size of the carbon black surface contains is not less 20nm or 40nm or less, and, DBP oil absorption amount 100 cm 3/100 g or more 260 cm 3 / A conductive roller having a weight of 100 g or less.
