Abstract
A plate shaped slim electrode is mounted on a carriage which supports an ink issuing unit and a charging tunnel, and is driven to travel in the lateral direction. A cylinder shaped rotary deflection electrode is rotatably mounted on the body of an ink jet system printer in a direction parallel to the travelling direction of the carriage. In a preferred form, a slit opening is formed in the center of the plate shaped slim electrode. The plate shaped slim electrode is maintained at the ground potential, whereas the rotary deflection electrode is connected to a high voltage source to establish a high voltage electric field between the plate shaped slim electrode and the rotary deflection electrode.
