Patent ID: 8241527

Claim:
A conductive seamless belt formed by extruding a conductive elastomer material as a sheet, wherein in said conductive elastomer material, carbon nanotubes are dispersed in a base component consisting of a polyester thermoplastic elastomer; said carbon nanotubes have diameters of 50 to 100 nm and an aspect ratio of 20 to 40; and said carbon nanotubes are added to said base component at a ratio of 0.5 to 5 parts by mass for 100 parts by mass of said base component, said sheet consisting of said conductive elastomer material has a volume resistivity of 10 6 to 10 10 Ω·cm and a variation in an in-plane volume resistivity thereof within 10 1 Ω·cm, in a flexing test conducted at a load of ½ lb, a flexing angle of 135 degrees, and a flexing speed of 175 cpm to examine a flexing resistance of said sheet, a number of flexed times is not less than 30,000 before said sheet is broken.
