ABSTRACT:
Disclosed is a method for preparing an original for projection by using a transfer film comprising a transparent plastic film substrate, an undercoating layer composed of an electrically conductive resin and having a surface resistance of 1.0.times.10.sup.6 to 9.0.times.10.sup.9 .OMEGA., and a toner receiving layer composed of a binder resin and having a surface resistance of 1.0.times.10.sup.10 to 1.0.times.10.sup.14 .OMEGA., which is formed on at least one surface of the transparent plastic film substrate through the undercoating layer.
An original for projection which is excellent in the surface smoothness and image characteristics can be obtained by electrostatically transferring an image of a one-component type magnetic developer on a photosensitive plate for the electrostatic photography, onto the toner receiving layer of the above transfer film and bringing the transferred developer image into contact with a roller under application of a pressure to fix the developer image on the toner receiving layer.
