Seamless semiconductive belt

摘要

The invention provides a seamless semiconductive belt produced by cutting a seamless tubelike film made of a polycarbonate containing conductive carbon to desired length at right angles to the axial direction of the film, the film having a surface electrical resistance of about 105 to about 1013 OMEGA / &squ& and the ratio of minimum surface electrical resistance to maximum surface electrical resistance being at least 0.01.
