ABSTRACT:
A copying apparatus for forming a hard copy image through an electrophotographic process includes an image forming apparatus which can form an image on a recording paper in various density levels, and a diagnostic unit for discriminating the image forming apparatus into three states of being capable of forming a proper image, being operable but incapable of forming a proper image, and being incapable of operation. Since the image forming states of the copying apparatus are divided into three stages, appropriate operation is performed in the copying apparatus using the electrophotographic process in response to the state of the machine.
