Abstract

PURPOSE: To prevent a density lowering after heat development by using a light source free from infrared rays as the light source of an apparatus for exposing a photoreceptor contg. a heat subliming composition and an original superposed on the photoreceptor to control a temp. rise of the original stand, intermediate paper, etc. in exposure.
CONSTITUTION: By contact-exposing intermediate paper 3 obtd. by coating base paper with a heat subliming photosensitive substance such as 4-methoxy-1-naphthol and original 2, a paper 3 part alone opposite to the image part of original 2 is activated. Paper 3 is then superposed on image receiving paper coated with org. silver salt, and by carrying out heat development, the substance in the unexposed part of activated paper 3 is heat sublimed and reacts with the silver salt, forming a silver image. As light source 5 for such contct exposure a light source free from infrared ray such as a fluorescent lamp having spectral wavelengths corresponding to the photosensitive region of the heat subliming composition is used.
