Semi-conductive composition for electrophotographic devices and semi-conductive members for electrophotographic apparatus using the same

摘要

PROBLEM TO BE SOLVED: To provide a conductive polymer for an electrophotographic apparatus which ensures a small variation in electric resistance in a wet hot environment and excels in conductivity.;SOLUTION: The conductive polymer soluble in an organic solvent is prepared by doping the following (A) component 1 with the following (B) component and (C) component, wherein a moiety (B component moiety) 2 introduced by the (B) component keeps ionic bond to an ionic moiety of the (A) component 1 through a sulfonic acid ion and a moiety (C component moiety) 3 introduced by the (C) component keeps ionic bond to an ionic moiety of the (A) component 1 through a sulfonic acid ion. (A) A π-electron conjugated polymer. (B) A compound having a sulfonic acid functional group comprising at least one of a sulfonic acid and a sulfonate group and a polymerizable functional group X. (C) A compound having a sulfonic acid functional group comprising at least one of a sulfonic acid and a sulfonate group and soluble in an organic solvent.;COPYRIGHT: (C)2008,JPO&INPIT
