Abstract (en)
[origin: EP0253560A1] An electrophotographic copying method comprises: using a copying apparatus having a positive-image copying system; forming toner images with a colored toner; transferring the toner images to colored paper of a different color to said colored toner; and fixing the transferred images to the paper, thereby providing a copy in which the lightness and darkness of images and the background of an original are formed in a reverse manner. Black insulation paper for use in this method and to which images produced by a colored toner are to be transferred and fixed to form images in which the lightness and darkness of images and a background are reversed has a surface specific resistance of 10<9> OMEGA or more and a volume specific resistance of 5 x 10<9> OMEGA . cm or more.
