ABSTRACT:
An image forming system includes a screen device having an image support element on which an image can be formed and a first scan unit optically scanning the image, and an image forming device, on which the screen device is arranged, which includes a document support element which can support a document thereon and a second scan unit optically scanning the document. The image forming device further includes a developing unit developing the electrostatic latent image pattern formed on an image carrier by light reflected from the image on the image support element and introduced into the image forming device from the image support element or by light reflected from the document arranged on the document support element thereby enabling the image forming system to copy not only the document arranged on the document support element but also the image formed on the image support element.
