After that, the plate 7 inverted by a motor 18 for inversion, and the functional color coating 12 on the plate 7 is allowed to oppose a substrate 1. A shutter 11 is opened, and in the case the plate 7 is heated to the sublimating temp. of the functional color coating 12 by a heating source, organic color particles reach the substrate 1 to form a photorecording coating layer. At this time, since the functional color coating 12 on the plate 7 is the dense and thin one and is good in thermal conductivity, bumping sublimation does not occur, and it occurs as face sublimation to make the directivity of the distribution of vapor mild, by which uniform coating can efficiently be formed on the substrate 1.
