PURPOSE: To form a beautiful embossed surface by using a waste powdery paint, by such a relatively simple process that a powdery paint is electrostatically adhered to the surface of an article to be processed as a thick layer and difference of altitude is provided to the formed powdery paint film before baking.

CONSTITUTION: After an electric field is provided between a powder painting apparatus 3 and an article 1 to be processed, a powdery paint 2 is electrostatically adhered to the surface of the article to be processed as a thick layer and, subsequently, treatment for providing difference of altitude, for example, by a spatula 4 is applied to said powdery paint film formed in an almost uniform thickness at this time while the treated paint film is baked to obtain an embossed surface. By this relatively simple process using a waste powdery paint, a beautiful embossed surface can be formed.
