Zusammenfassung:PURPOSE:To prevent a walk of a belt member, so that edge force can be reduced, by forming partly a plurality of rollers, winding the belt member linked, into an elastic roller working an external diameter of an elastic fin to provide fixed directivity, and setting a working direction of elastic fin of at least the one elastic roller to a reverse direction to the other. CONSTITUTION:In a color electrophotographic copying machine, a belt member 8 of conveying a recording sheet 3 is linked around over a drive roller 4, which is a metal-made roller, edge guide roller 5 and driven rollers 6, 7. Here is used an elastic roller 20 in the edge guide roller 5 and the driven rollers 6, 7. This elastic roller 20 is formed into diskshaped elastic fins 22 along an axial direction of a rotary shaft 21, that is, the fins 22 vertically providing a plurality of disk fins, and a working direction of the elastic fin 22 of the elastic roller 20, used in the driven rollers 6, 7, is set to the direction toward a front side from a rear side of the copying machine, to set that of the elastic roller 20 as the edge guide roller 5 to the reverse direction.
