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 producing 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 used in image forming apparatuses such as copiers, printers, facsimile machines and the like. Background technique [0002] As for the method of charging an elastomer, the following two methods are generally used: In one 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, ionically conductive polymer compositions such as butadiene rubber, acrylonitrile butadiene rubber, epichlorohydrin rubber, and the like are used. [0003] When constituting a c...
