Abstract
A voltage is applied between first and second deflecting electrodes from a deflecting voltage controller, whereby an electric field is formed between the first and second deflecting electrodes in a direction perpendicular to electrode surfaces. An electric line of force is generated from a direction perpendicular to the electrode surface of the first deflecting electrode and made perpendicularly incident on the electrode surface of the second deflecting electrode. Since the first and second deflecting electrodes are parallel to each other, a plurality of parallel electric lines of force are formed perpendicularly to the electrode surfaces of the first and second deflecting electrodes. Droplets after passing charged electrodes fly in a region where this deflecting electric field is formed, whereby charged droplets are deflected in a direction in which the charged droplets approach the second electrode having opposite charging polarity. The charged droplets form a printing pattern.
