<P>PROBLEM TO BE SOLVED: To provide an electroconductive fiber obtained by more heightening the electroconductivity which has been insufficient, having very little unevenness of the electroconductivity in the fiber length direction, and having high electroconductivity on the fiber surface by eliminating problems such as fluidity insufficiency and spinnability insufficiency of a polymer, and reduction of a fiber strength caused by the addition of an electroconductive agent of a conventional technique, and providing a uniform clear image when incorporated in a laser printer by being formed into a brush because of the uniform electroconductivity by the little unevenness in thicknesses among single fibers. <P>SOLUTION: The electroconductive fiber is obtained by forming at least a part of the electroconductive layer out of a resin composition containing the electroconductive agent in an aromatic polyester resin composition obtained using a diol component having a 9,9-bisphenylfluorene skeleton as a copolymer component. <P>COPYRIGHT: (C)2010,JPO&INPIT |
