ABSTRACT:
An imaging device for use in an electrographic imaging process, without a cleaning unit for residual toners, which comprises an image-carrying element, an image exposure means, a developing means, an image transfer means, and a distribution roller means of an elastic and electrically conductive material for uniformly distributing the residual toners over a surface of the image-carrying element and at the same time deelectrifying and recharging the same surface of said element. The imaging device has a simplified and compact structure and does not cause an environmental pollution problem due to the generation of ozone in the device.
