Abstract
In an image forming apparatus provided with an image transporting belt that holds an image directly or indirectly and is laid on a plurality of tension rolls thereby to move circularly, and a sub-unit having a rotary roll that comes into contact with this image transporting belt and is rotationally driven by a drive section, the drive section includes a drive source, and an elastic drive power transmitting member that transmits drive power from the drive source and absorbs difference in peripheral speed produced between the image transporting belt and the rotary roll. The drive section includes a slip transmission member that engages with the elastic drive power transmitting member and slips under a condition over a peripheral speed difference absorbable range of the elastic drive power transmitting member.
