PURPOSE: To simplify separation of the organic substance according to an image by making a substrate come into contact with an electrically conductive solution of an organic substance, using the substrate as one electrode and depositing the organic material on the substrate at a specified current density, with impulse current.

CONSTITUTION: In this method, a substrate 2 is allowed to contact with a conductive solution 3 of an organic substance and a DC voltage 7 is applied to between the substrate 2 and at least one electrode. At this time, if necessary, the substrate 2 is connected to a power source as an anode or cathode and the organic substance is deposited on the substrate at an about 0.01 to 100A/dm2 current density with impulse current. Thus, various kinds of resins can be deposited according to an image on the substrate 2 from the aqueous solution 3 which is not required to contain any organic solvent or a large amount of any other auxiliary agent that may cause environmental pollution.
