常にむつかしく。[Detailed Description of the Invention] Technical field: The present invention is a magnetic recording method using a magnetic fluid as an image display material, in which a magnetic latent image formed on a substrate surface based on an image signal of 1 in 9% is visualized using a magnetic fluid. Technology related to the magnetic recording method for transferring this onto a transfer medium: Magnetic fluid is a colloidal solution in which ferromagnetic powder of about 100X is suspended in water or an organic solvent. A recording device has already been developed that utilizes this characteristic of Q magnetic fluid, which has unique fluidity and the property that the liquid level rises in a magnetic field and forms needle-like protrusions in the direction of the magnetic field lines, and uses this as ink. ing. for example,
Japanese Patent Publication No. 49-17746 discloses a method in which a magnetic fluid is supplied to a surface on which the magnetic fluid can be uniformly adhered, and a recording paper is inserted between the surface and a magnetic head placed opposite to the surface to drive the magnetic head. A magnetic recording method has been disclosed in which a magnetic fluid is transferred to a recording paper side according to an image signal by driving. However, it is very difficult to uniformly adhere the magnetic fluid to the entire surface due to the surface tension and viscosity of the magnetic fluid.

体表面の非画像部に付着し画像を乱すおそれが生じる。Therefore, even if an attempt is made to record by driving the magnetic head, there is a drawback that image disturbances such as one character cutoff and white spots occur. For example, in the magnetic recording method disclosed in Japanese Patent Application No. 58-97714, a magnetic latent image on a ferromagnetic substrate is developed with a magnetic fluid, a transfer paper is applied to the magnetic fluid image, and the transfer paper is pressed from the back side with a roller. The image is transferred by pressing with the paper. According to this method, the pressure roller is always urged toward the surface of the substrate. Therefore, when the transfer paper is fed and there is no rice, excess magnetic fluid on the surface of the substrate adheres to the pressure roller, which causes stains on the back of the transfer paper and, in turn, stains on the recorded image.Moreover, the biasing of the pressure roller is uneven. Alternatively, uneven pressure may be avoided, which may cause the finally obtained recorded image to become unclear. moreover,
In order to avoid the above disadvantages, if you try to transfer using a transfer charger, if the magnetic fluid is insulating, the magnetic fluid will adhere to the non-image area of the substrate surface due to the residual charge due to the influence of the transfer charger, and the image will not be printed. There is a risk of disturbance.

The magnetic fluid 2 is a colloidal solution of ferromagnetic particles dispersed in an insulating solvent. Examples of the ferromagnetic particles include magnetite, cobalt-ferrite, nickel-ferrite, manganese-ferrite, barium-ferrite, and nickel-zinc-ferrite. Ferrite, iron.

磁性流体画像は記録紙などの転写媒体７に転写される。It is obtained by dispersing powders such as 06, Fe, Go, Hi, etc. in a resin. A magnetic helad 4 is arranged near the surface of the base 3. The magnetic radar 4 is driven by an output from an analog modulation circuit 6 that fully modulates the image signal 5, and forms a magnetic latent image on the surface of the ferromagnetic substrate 30 in accordance with the image signal. Ferromagnetic substrate 3 having a magnetic latent image on the surface
is developed and visualized by the magnetic fluid 2. The magnetic fluid image on the substrate 3 is transferred to a transfer medium 7 such as recording paper.

が送り込まれないときには。This transfer is performed by charging the back surface of the transfer medium 7 with an electrostatic charge by a transfer charger 8 such as a corona charger provided behind the transfer medium 7, thereby causing an inverse charge on the back of the ferromagnetic layer 32, that is, on the surface of the conductive support substrate 31. By inducing polar charges, the transfer medium 7 is transferred to the ferromagnetic layer 3 by the Coulomb force of both charges.
This is done by pressing the two surfaces together. Transfer medium 7

ない。The charge from the charger 8 is simply transferred to the magnetic fluid on the surface of the ferromagnetic layer 32, and unlike the conventional method, dirt on the base surface in the area where the transfer medium has not passed will adhere to the pressure roller, and this will eventually cause the transfer medium to There is no risk of contamination.

。このようにして磁気記録の一工程が終る。基体３は次
のサイクルに備えられる。The base body 3 is further rotated, and the magnetic fluid remaining on the base body surface is removed by the cleaning blade 9. The magnetism remaining on the surface of the substrate is also erased by the degaussing head 11. Residual charges on the surface of the substrate are erased by a charge eliminating charger 12 such as A, C, or corona charger near the substrate 3. In this way, one step of magnetic recording is completed. The substrate 3 is ready for the next cycle.

はばみ、その結果、磁性粒子画像の転写が必ずしも効果
的に行なわれない。The substrate 3 emerging from the development zone of the container 1 is provided with a carrier liquid layer of magnetic particles. This liquid layer hinders the close contact between the transfer medium 7 and the magnetic particle layer due to its surface tension, viscosity, etc., and as a result, the magnetic particle image is not necessarily transferred effectively.

イーズによりキャリア液体を画像を乱すことなく。Therefore, as shown in FIG.
3 is arranged near the base body 3 on the downstream side of the developing area, that is, on the downstream side of the magnetic fluid 2 in the container 1 . This corona charger 1
3, the insulating carrier liquid is charged. The charged liquid is squeezed by the Coulomb force between it and the charges of opposite polarity induced on the surface of the base 3. Since the base body 3 is rotating, the liquid layer is squeezed along the rotation direction. This squeezes the carrier liquid without disturbing the image.

７と磁性粒子画像との密着を実質的にはばまない。それ
ゆえ、良好な転写画像が得られうる。Excess liquid is removed to a suitable layer thickness. When the carrier liquid has a minimum layer thickness necessary for transferring magnetic particles, its influence on the outside due to its surface tension and viscosity becomes minimal, and the close contact between the transfer medium 7 and the magnetic particle image is not substantially hindered. Therefore, a good transferred image can be obtained.

像を乱すという問題も完全に解消される。Effects of the Invention: According to the method of the present invention, the magnetic fluid image on the substrate 3 is transferred to the transfer medium 7 by the action of the transfer charger 8, which presses the transfer medium 7 against the surface of the substrate 3 by Coulomb force. Therefore, the problem of incomplete image transfer due to contamination of the transfer medium by the pressure roller or uneven pressure, as in the conventional pressure transfer method, is completely eliminated. Since residual charges on the substrate surface are completely erased by the static elimination charger 12, the problem of magnetic fluid adhering to non-image areas of the substrate surface during development and disturbing the image is also completely eliminated.

As a result, the carrier liquid on the substrate 3 is appropriately squeezed, excess liquid is removed, and an appropriate layer thickness is obtained, so that image transfer can be performed smoothly. With the method of the invention it is therefore possible to obtain clear and high quality recorded images. Moreover, the apparatus for carrying out the method of the invention is extremely simple in construction and operation.
