<p>PURPOSE:To allow one side part of a conveyer belt stretched between conveyer rollers to surely abut against a flange so as to positively prevent the conveyer belt from meandering, by making the diameter of at least a part of one of the conveyer rollers, near to one end part thereof, less than that of the remaining main part thereof. CONSTITUTION:A sheet fed from a sheet loading bed 7 conveyed to a predetermined position on a predetermined member in an image forming device by means of a conveyer belt stretched between conveyer rollers 17, 19. During the conveyance, both side parts of the conveyer belt 16 bends on the small diameter sides 17b, 19b of the conveyer rollers 17, 19 so as to surely abut against flanges 17a, 19a. With this arrangement, even though the diameters of the flanges 17a, 19a are slightly larger than that of the conveyer rollers 17, 19, the conveyer belt 19 can be prevented from meandering, thereby it is possible to surely convey a sheet fed from the sheet loading bed 7 onto the predetermined member in the image forming device.</p> |
