Abstract
Provided is a shaft made of a fiber-reinforced resin, in which a continuous glass fiber bundle is embedded in parallel with a lengthwise direction of the shaft, the shaft including a matrix resin formed of a resin composition comprising (A) a thermosetting resin as a main component, (B) carbon black, (C) a dispersant having a basic functional group, and (D) a curing agent for the component (A), in which the component (B) is particulate and is distributed along continuous glass fibers constituting the continuous glass fiber bundle. Thus, there can be provided a conductive shaft that is lightweight, has high strength, is excellent in conductivity, and is inexpensive, and a conductive roll for OA equipment using the shaft, and a method of producing the conductive shaft.
