Abstract
Abstract An electronic imaging apparatus such as an electrophotographic copying machine comprises an image forming device for forming an image corresponding to the image of an original, an image agent supply for supplying an image agent to the image forming device, a developer for developing the image formed by the image forming device, and a recycle device for recycling the imaging agent which has not been used for the image forming process by the image forming device, the image agent supply being further responsive to the recycle device for receiving the recycled image agent gathered by the recycled device.
