PURPOSE:To obtain an image with high sensitivity and good contrast, by constituting an image receiving layer on a surface (irradiated surface) dispersed in a hydrophilic binder, an oil drop in which an another substance among two kinds of substance capable of giving rise to interact with each other is contained in an org. solvent in a dissolved state. CONSTITUTION:The image receiving layer 13 is constituted of the layer dispersed in the hydrophilic binder, the oil drop 15 in which the another substance among two kinds of the substances capable of giving rise to interact with each other, is contained in the org. solvent in the dissolved state. Accordingly, the image receiving layer 13 has high transparency. And, said layer 13 is destroyed an emulsion state which is relatively uniform by heating, thereby making translucency. The light transparency of said layer 13 after forming the image reduces comparing with the light transparency before heating. Thus, the exposure of the photosensitive layer is realized with good efficiency (high sensitivity). As the silver turbidity of said layer 12 is suppressed by changing said layer 13 to the light transparency, the reduction of an image quality is controlled in a nonimage part, thereby obtaining a clear image with good contrast. |
