PURPOSE:To stably execute a clear high resolution image recording at a high speed by staggeredly providing various magnetic substances in the arraying direction of a recording electrode having various magnetism in contact with a conductive magnetic developer on a recording member. CONSTITUTION:A permanent magnet 2 which is a magnetic field generating means is arranged still inside the recording member 1 and always forms a certain magnetic field. Many recording electrodes 3 which are arranged to have a gap with the recording member are arrayed in row on an insulative substrate 4 which is made of, for example, a ceramic or an epoxy resin, etc. The recording electrodes 3 are formed by a permalloy, a nickel, etc., which are magnetic members so that they have equal magnetism. And in this arraying direction, the magnetic substance 5 is staggeredly arranged alternately between every recording electrode and itself through an insulating layer. Consequently, the aggregate of the conductive magnetic developer in a flux state, which is independent, and does not receive an affection from the adjoining recording electrode, can be always stably made to exist in every recording electrode. Thus, the clear high resolution image can be stably recorded. |
