An electrostatic recording head for causing a developing agent to be electrostatically deposited on the surface of a recording member in accordance with a recorded image, comprising a recording electrode having a plurality of linear electrodes arranged in a common plane at a predetermined interval; a magnet disposed at one side of the recording electrode; and a magnetic member disposed at the side of the recording electrode opposite to the magnet; the magnet being disposed such that the magnetic lines of force pass through the end of the recording electrode towards the portion of a recording member opposed by the end of the recording electrode. The present invention also relates to a method of producing this electrostatic recording head. The invention also is concerned with an image recording apparatus which employs this electrostatic recording head, as well as with a developing agent supplying device and a display device.
