<p>PURPOSE:To provide a seamless belt having excellent durability and high roundness to be used for an electrophotographic copying machine, laser printer, etc. CONSTITUTION:This seamless belt tube for electrophotography consists of the following thermoplastic resin compsns. (a) to (c) and (a), (b) and (c) denote thermoplastic polyalkylene terephthalate, thermoplastic aromatic polycarbonate and carbon black respectively. The compounding ratio of the compsn. (a) is 50-95wt.% of (a)+(b), (b) is 50-5wt.% of (a)+(b), and (c) is 5-25 pts.wt. to 100 pts.wt. of (a)+(B). The surface conductivity of this belt 6 on the top surface 6b and the back surface 6a is 1X10<0>-1X10<13>OMEGA/square.</p> |
