Abstract
An endless conveyor belt that has a nonexpansible and noncontractive core member and an elastic laminate layer bonded to one of the core surfaces. The core member and the laminate layer are preformed as an endless belt, respectively, and bonded together to constitute an endless conveyor belt. The conveyor belt is used for conveying an original paper to a predetermined position on a contact glass where the original paper is operated a predetermined treatment. The conveyor belt is assembled within an ADF in cooperation with belt rollers to rotary drive the conveyor belt. The belt is formed by a method that includes: a core belt forming process in which an endless core belt is formed from a nonexpansible and noncontractive material; a laminate layer forming process in which a laminate layer in a form of an endless belt is formed from an elastic thermoplastic material; and a bonding process in which the laminate layer is bonded to at least one of the surfaces of the endless core belt.
