<P>PROBLEM TO BE SOLVED: To provide a semiconductive seamless belt in which aggregation of carbon black is suppressed and which can prevent the reduction of electric resistance value by time degradation of the belt and the occurrence of defects on an image due to the reduction, and excels in durability. <P>SOLUTION: The seamless belt comprises a polyimide resin composition containing carbon black, wherein the difference between surface resistivity (logΩ/sq.) and volume resistivity (logΩ cm) measured at an applied voltage of 100 V is within 1.5. <P>COPYRIGHT: (C)2008,JPO&INPIT |
