Abstract

Laminate, of photographic negative or positive layer with transparent inter-layer and photo-conductor layer, is exposed through side of negative (or positive) to form electro-static image in photo-conductor layer which is transferred by toner to reception sheet to obtain positive/positive copy. Arbitrary number of copies may be produced, without use of optical system, the copies being very sharp as only contact-printing process is involved.
