ABSTRACT:
An electrophotographic copying apparatus comprises an image forming unit for forming an image of an original to be copied, and a developing device for transferring the image onto copy paper, the image forming unit including a scorotron charger for representing only outlines of the original image. When the original is copied with a cover being not placed thereon, a shadow would be usually formed in an area corresponding to the portion not covered; however, the scorotron charger forms an outline image of this shadow and accordingly no shadow is formed in the area corresponding to the portion not covered.
