Dry developing method of photosensitive material

Abstract

Abstract PURPOSE:To improve the workability in a dry developing method by oscillating a pigment relatively with the film surface of a photosensitive material and sticking the pigment to the surface of the photosensitive material. CONSTITUTION:A photosensitive material of which the power to receive a pigment when exposed changes is exposed imagewise and if necessary the image part is subjected to a treatment to increase the pigment accepting power and thereafter the pigment is stuck thereto. The photosensitive material after image exposure is first placed in such a way that the film surface faces downward in a vat laid with the pigment and the photosensitive material is pressed to the pigment layer if necessary in the above-mentioned method. The pigment is then oscillated relatively with the film surface of the photosensitive material to stick the pigment to the surface of the photosensitive material and thereafter the pigment sticking to the non-image part of the photosensitive material is removed.
