Abstract:
A semiconductive belt comprising a polyimide film and carbon black as a conductive filler, said film having a moisture absorption and swelling coefficient of 2.0/10.sup.5 cm/cm/% RH or less, a volume resistivity of 10.sup.9 .OMEGA.cm to 10.sup.16 .OMEGA.cm and a surface resistivity of 10.sup.10 .OMEGA. to 10.sup.17 .OMEGA. at 25.degree. C. and 60% RH, wherein the amount of change of the surface resistivity between 30.degree. C. and 85% RH and 1 0.degree. C. and 15% RH in terms of common logarithm is 1.0 or smaller.
