Patent ID: 7150908

Claim:
A conductive belt comprising: an electroconductive base layer made of a resin; an ionic-conductive intermediate layer made of an elastomer; and a surface coating layer, wherein a tensile modulus of elasticity of said base layer is set to not less than 500 Mpa, and a volume electric resistance value thereof is not less than 10 6 Ω·cm nor more than 10 11 Ω·cm; said intermediate layer is formed on an upper surface of said base layer, has a JIS A hardness less than 70, a thickness not less than 50 μm nor more than 600 μm, and a volume electric resistance value not less than 10 8 Ω·cm nor more than 10 14 Ω·cm; said intermediate layer is composed of a polyurethane elastomer containing a polyol containing polypropylene glycol or/and a hydroxyl-terminated liquid rubber moiety as a main component thereof and an aromatic moiety or/and a polyol moiety; and said surface coating layer is made of a rubber, an elastomer, or a resin.
