PROBLEM TO BE SOLVED: To provide a recording electrode for achieving recording of high quality free from irregularity. SOLUTION: An aperture electrode 1 is constituted of an insulating film with a thickness of 50μm and a first stepped part 8 having an aperture part 4 with a thickness of 25μm formed thereto and a second stepped part 9 with a thickness of 15μm not coming into contact with the toner carrying roller 11 are provided in the longitudinal direction of the aperture electrode. When the aperture electrode 1 receives some external force at a time of handling, the external force appears as strain in the second stepped part 9 being the part lowest in rigidity of the aperture electrode 1 and the presence of wrinkles or breakage is eliminated in the first stepped part 8 and printing irregularity of recording is eliminated. |
