PURPOSE: To improve the adhesion of a photosensitive recording sheet to a light transmitting original and to increase the resolution of a copied image by piercing many fine vent holes in the recording sheet.

CONSTITUTION: Photosensitive and pressure sensitive recording paper 1 has many fine vent holes 1a and photosetting microcapsules applied to one side in a dispersed state. The paper 1 is drawn out of a cassette case 2 and a light transmitting original 9 is superposed on the paper 1 on an exposure stand 10. The air in the internal space 10c of the stand 10 is exhausted by normally rotating a motor 11 to facilitate the adhesion of the original 9 to the paper 1 through the holes 1a in the paper 1 and the microcapsules of the paper 1 in the light transmitting region are set by irradiation with light from a light source 7. The original 9 is then separated by reversely rotating the motor 11 and the paper 1 is sent between pressing rollers 13, 14 and pressed together with a developing sheet 18. The unset microcapsules of the paper 1 are destroyed and a transferred image is formed on the sheet 18.
