ABSTRACT:
Disclosed is a method for producing an original for use in an overhead projector through an electrophotographic process. The method comprises a process for applying a first light-transmissive toner onto a surface of a transparent film, a process for heat-fixing the first light-transmissive toner on the film so that particles of the first light-transmissive toner are not melted completely and such that a diffusive surface is formed, a process for applying a second light-transmissive toner onto the diffusive surface corresponding to a document image, and a process for heat-fixing the toner image on the diffusive surface so that particles of the second light-transmissive toner forming the toner image are melted completely and that a toner image having a smooth surface is formed. When such films carrying toner images having a smooth surface formed on the diffusive surface are piled one over another, the toner images on the lower films placed under the top film are invisible through the top film and hence the toner image on the top film is clearly visible.
