Zusammenfassung:	A coupler for transferring rotary motion from a drive gear to a photoconductive drum or ITM belt within an image forming apparatus. In one embodiment, the coupler includes a substantially cylindrical body having first and second ends having extensions extending outward for mating respectively with the drive gear and photoconductive drum. One surface of each of the extension may include a rounded drive surface. One end of the coupler may further include a wall that mounts against a dome extending outward from one of the drive gear or photoconductive drum. One of the drive gear or photoconductive drum may further include axially aligned ridges that are straddled by the coupler to allow for the coupler to axially slide and maintain contact with the photoconductive drum and drive gear even during misalignment.
