Abstract

PURPOSE:To prevent reduction in charging performance due to ink stain on a charging electrode of an ink jet recorder by providing the charging electrode with a coil-shaped conductor and an ink absorber member which covers the conductor. CONSTITUTION:In a metal cylinder 7a having flanges at its both ends, a coil spring 7c is so arranged as to surround the flying path of an ink flow from an ink jet head 1, and a cylindrical fibrous filter 7b is so arranged as to cover the spring 7c. The cylinder 7a is formed with an ink discharge hole, a relay pipe 7d is connected with the hole, and a short ink guide pipe 7e is connected with the pipe 7d. By this, the spill of ink flow upon starting and stopping of ink injection is absorbed by the filter 7b through the curbed surfaces of the spring 7c and the excess portion drops from the pipe 7e, so that the electric field of the spring 7c can always be kept constant.
