Abstract

A conductive thermoplastic elastomer composition comprising a component (A) containing a thermoplastic resin or/and a thermoplastic elastomer; a component (B) comprising an ionic-conductive agent containing an ethylene oxide-propylene oxide copolymer or/and an ethylene oxide-propylene oxide-allyl glycidyl ether copolymer and a metal salt contained in the ethylene oxide-propylene oxide copolymer or/and the ethylene oxide-propylene oxide-allyl glycidyl ether copolymer; and a component (C) comprising an ethylene-acrylic ester-maleic anhydride copolymer.

Description

Technical field [0001] The present invention relates to a conductive thermoplastic elastomer composition, a method for preparing the conductive thermoplastic elastomer composition, and a molded article formed by processing the conductive thermoplastic elastomer composition. More particularly, the present invention relates to a conductive thermoplastic elastomer composition effectively used as a conductive roller in an image forming apparatus such as a copying machine, a printer, a facsimile machine, and the like. Background technique [0002] Regarding the method of charging the elastomer, the following two methods are generally used: In a known method, a conductive polymer composition containing a conductive filler such as metal oxide powder, carbon black, etc. in its polymer is used. In another known method, an ion conductive polymer composition such as butadiene rubber, acrylonitrile butadiene rubber, chlorohydrin rubber, etc. is used. [0003] When a conductive polymer compos...
