<P>PROBLEM TO BE SOLVED: To provide a roll belt for electrophotographic equipment using an electrically conductive polymer available at low-cost and superior both in electrical conductivity and solubility. <P>SOLUTION: The roll belt for electrophotographic equipment has a coating film formed by crosslinking a semiconductive composition containing the electrically conductive polymer which is solvent soluble and is obtained by imparting electrical conductivity to a π-electron conjugated polymer (A) by means of a dopant (B) and a nonconjugated polymer as essential components. The π-electron conjugated polymer (A) is prepared by polymerizing at least one monomer selected from the group consisting of aniline, pyrrole, thiophene and derivatives of these. The dopant (B) comprises an alkylbenzenesulfonic acid or its salt having ≥2 alkyl substituent groups, wherein a total carbon number of the alkyl substituent groups is 10-37. <P>COPYRIGHT: (C)2007,JPO&INPIT |
