Abstract
A belt driving apparatus for carrying material to be recorded to a plurality of image recording units. In the belt driving apparatus, the distance of movement of material to be recorded corresponding to one rotation of the belt driving roller has been set to n (an integer)-times (where n=2, 3, 4 . . . ) as long as a distance between each image recording unit. A distance between one image recording unit and another recording unit is equal to or an integral fraction of .pi.(D+2 t), wherein D is the diameter of a drive roller driving the belt and t is the thickness of the belt.
