Abstract
The present invention provides a conveying apparatus comprising a plurality of rotary members; a frame for supporting the plurality of rotary members; and an endless belt wound around the plurality of rotary members and moved by rotation of the rotary members to convey a sheet, the belt including a core embedded within the belt and formed by weaving threads extending in a circumferential direction of the belt and threads extending in a widthwise direction of the belt; and wherein, in order to cancel a deflection force of the belt generated by the cause of distortion of the frame when the rotary members are rotated to shift the belt, each of the threads extending in the circumferential direction in the core has a constant twist direction to generate a deflection force opposite to the aforementioned deflection force.
