PURPOSE:To prevent a conveyor belt from shifting laterally or longitudinally and to eliminate the transfer shift of a color image by fixing a filmy reinforcing material to the belt base cloth of a transfer material conveyor belt and also fixing a guide rib corresponding to the reinforcing member, and giving the conveyor belt rigidity. CONSTITUTION:The conveyor belt 100 is formed by fixing the reinforcing material film sheet 100B to one end part of belt base cloth 100A made of screen meshes and further fixing the guide rib 10C thereupon. The fixation positions of the reinforcing material film sheet 100B and guide rib 100C to the belt base cloth 100A are not positions where the transfer material of the belt base cloth 100A is conveyed and correspond to guide grooves 11b-14b and 104b of rollers 11-14 and a backup roller 104. Thus, the guide rib 100C is fixed to the reinforcing material film sheet 100B which has rigidity and high tensile strength while facing the respective guide grooves, so the rib faces a thrust force operating on the conveyor belt 100 and maintains perpendicularity, so that the conveyor belt 100 is prevented from being shifted laterally or longitudinally.
