PURPOSE:To increase fidelity of a duplicator and the like, by a method wherein a sheets conveyance belt provides high surface friction action against a document, provides low friction action against the surface of a vacuum sucking device, and provides excellent resistance properties against a tensile force. CONSTITUTION:A sheet conveyance belt 1 has a chlorinated skin layer on the one surface of a rubber belt having a friction factor mu of 1.0 or more. Since it is imperative that a belt 1 has excellent tensile resistance properties, it is prepared so as to have hardness of about 50 or more and about 70 or more. In order to manufacture the sheet conveyance belt 1 with highmost efficienty, after a rubber belt is formed using a rubber composition so prepared as to have vulcanized rubber hardness of 70 or less, the belt is immersed in a chlorine solution for a given time so that a surface friction factor mu is adjusted in a range of 0.5-0.3. Thereafter, a method, wherein the one surface of the belt is ground to remove a chlorined skin layer, is employed.
