PURPOSE:To perform the printing of a large area at a high speed by a simple structure without using a nozzle, by providing an image forming part having a structure for forming a conductive ink layer on a conductive substrate and applying bias to needle electrodes through an image forming body corresponding to an image. CONSTITUTION:A conductive liquid ink layer 2 is formed on a conductive substrate 1 and needle electrodes 4 are arranged in such a state that an image forming body 3 is placed on the ink layer 2. Next, a bias control switch 5 is turned ON/OFF corresponding to a printing pattern. As the image forming body 3, a material regarded as a dielectric body such as paper, a plastic film or leather is used and, therefore, an inexpensive full color printer is formed. |
