SEMICONDUCTIVE COMPOSITION FOR ELECTROPHOTOGRAPHIC APPARATUS, AND SEMICONDUCTIVE MEMBER FOR ELECTROPHOTOGRAPHIC APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a semiconductive composition for electrophotographic apparatuses exhibiting excellent controllability of electric resistance. SOLUTION: The semiconductive composition for electrophotographic apparatuses comprises (A) below as an essential ingredient: (A) an electroconductive polypyrrole obtained by allowing a polypyrrole, having a structural unit represented by general formula (1), wherein R1is a 1-50C alkyl group; R2is a 1-50C alkyl group; and n is a positive number, to have electroconductivity using a dopant having a sulfonic group or a sulfonic acid salt structure.
