Abstract: PURPOSE:To provide the transfer material carrying member having excellent mechanical property, wear resistance, electrical durability and lubricity by incorporating a copolymer having specific constituting units into the member. CONSTITUTION:This transfer material carrying member contains the copolymer which is the constituting unit expressed by formula I and the constituting unit expressed by formula II and in which the constituting unit expressed by the formula II is 0.1 to 50wt.% of the total weight of the copolymer as well as conductive particles. In the formulas, A denotes 1 to 10C straight chain, branched chain or cyclic alkylidene group, aryl substd. alkylidene group, arylene dialkylidene group, -O-, -S-, -CO- or -SO- or -SO2-; R1 to R4 denote hydrogen, halogen, 1 to 4C alkyl group or alkenyl group. R5 denotes 2 to 6C alkylene group or alkylidene group; R6 and R7 denote 1 to 3C alkyl group, phenyl group or substd. phenyl group; n denotes an integer from 1 to 200.
