The invention provides a molding formed of a thermoplastic elastomer composition which molding exhibits suppressed compression set and satisfactory tensile strength while exhibiting low hardness.The molding is formed of a thermoplastic elastomer resin composition comprising; an aromatic vinyl-isoprene block copolymer (a) including two or more poly(aromatic vinyl) blocks each having a weight-average molecular weight of 14,000 to 100,000, in an amount of 55 to 95 wt %; an aromatic vinyl-isoprene diblock copolymer (b) in an amount of 0 to 40 wt %; and polyisoprene (c) having a weight-average molecular weight of 5,000 to 300,000, in an amount of 5 to 33 wt %; wherein the composition has an aromatic vinyl monomer unit content of 14 to 30 wt % based on the total amount of the components (a), (b), and (c).The molding can be widely employed in a variety of uses where the characteristics of the product are advantageous; such as roller members (e.g., a transport roller and a feed roller) used in OA machines and office machines.
