An image forming apparatus comprising an accumulator drum for receiving toner images from a plurality of imaging units and transferring the toner images to a receiving media. The basic components of the image forming apparatus comprise an accumulator drum having a plurality of imaging units with photoconductive drums positioned about the accumulator drum, and a laser assembly. In one embodiment, a laser emits light beams for forming a latent image on each of the photoconductive drums with each light beam having a different external optical path length. In one embodiment, a drive mechanism operatively connected to the imaging units drives the accumulator drum. In one embodiment, the imaging units are positioned about the accumulator drum is a specific angular placement. In one embodiment, the imaging units are at least partially positioned within the interior of the accumulator drum.
