2. Description of the Related Art Techniques such as electrophotography, electrostatic recording, and electrostatic printing have been commonly used as methods for reproducing documents, figures, and the like. For example, in electrophotographic copying machines and facsimiles, after an electrostatic latent image is formed on a photoconductor layer or dielectric layer, toner or resin is charged to a predetermined polarity by frictional charging with a carrier using a magnetic brush method. A recording method in which a developed image is obtained by selectively adhering a magnetic toner containing magnetic powder as a main component is often employed. However, in this recording method, it is necessary to provide a latent image forming means in addition to the developing means within the recording device.
There are problems in that the device tends to become more complicated and larger. Therefore, for example, as described in Japanese Patent Publication No. 55-30228, conductive magnetic toner is magnetically attracted and held on a non-magnetic conductive sleeve.
A sheet-shaped recording member is passed between this conductive sleeve and a recording electrode placed opposite it, and an information signal is applied to the recording electrode to generate an electrostatic force on the toner and cause the toner to be transferred onto the recording member. Selective attachment is provided. Regarding direct recording methods, many other proposals have been made, but all of them involve passing a recording member between a recording electrode and a counter electrode and recording only by electrical means. Therefore, in order to obtain good recorded images, it is necessary to strictly specify various conditions such as the gap between the electrodes and the amount of toner supplied onto the recording member, especially when plain paper is used as the recording paper. Since the surface resistance of the paper is greatly affected by environmental conditions such as humidity and temperature, it is necessary to adjust the developing conditions according to the environmental conditions, and there are also problems such as the inability to perform high-speed recording, so it has not been put into practical use yet. has not yet been reached.

SUMMARY OF THE INVENTION An object of the present invention is to provide a recording method that eliminates the above-mentioned drawbacks of the prior art and allows a sufficiently practical directly recorded image to be obtained with a simple mechanism.

Below the non-magnetic sleeve 4, a non-magnetic guide member 6 is provided for holding the recording paper 5, which is made of zinc oxide paper or the like with a photoconductive layer formed on its surface, in a predetermined position relative to the non-magnetic sleeve 4. is located. The guide member 6 may be a non-magnetic metal plate with a thin slit formed in the light irradiation portion, or may be made entirely of a translucent material such as Nesa glass. 7 is an optical signal such as a laser beam irradiated from the back surface of the guide member 6. 8 is a corotron for uniformly charging the surface of the recording paper.

First, the surface of the recording paper 5 is uniformly charged by the corotron 8, and then the recording paper 5 is conveyed in the direction of the arrow shown in the figure and supplied to the gap d formed between the nonmagnetic sleeve 4 and the guide member 6.
On the other hand, the non-magnetic sleeve 4 is rotated relative to the permanent magnet 3, for example, the non-magnetic sleeve 4 is fixed, the permanent magnet 3 is conveyed in the direction of the arrow in the figure, and the magnetic toner 2 is conveyed in the direction of the arrow in the figure.

The optical signal passes through the guide member 6 and the recording paper 5 and reaches the surface of the recording paper 5. Therefore, recording paper 5
At the same time, the charge on the surface of the optical signal irradiation area is removed, and at the same time, the magnetic toner 2 adheres to the area other than the optical signal irradiation area, that is, the charged area, so that a so-called reversed image is obtained. In this case, the magnetic toner preferably has a volume resistivity of 10 2 to 10 9 Ωcm, preferably 10 2 to 10 4 Ωcm.

In the recording method of the present invention, a recording paper whose surface is uniformly charged in advance is used as described above, and a latent image is formed by irradiation of an optical signal from the back surface of the recording paper in the recording area. This is because paper that is relatively white, such as zinc oxide paper, has considerable translucency, so that a large amount of light incident from the back surface of the paper reaches the front surface of the paper. Additionally, regarding the diffusion of light signals inside the paper when it passes through the paper, optical means such as slit exposure used in normal copying machines can easily blur the light image and reduce resolution. However, if optical means such as a narrowly focused laser beam is used, diffusion within the paper will not be a problem and an optical signal with sufficient resolution can reach the vicinity of the surface of the recording paper.

In Figure 1, the recording paper 5 has a thickness of approximately 80 μm.
Zinc oxide paper was used, and its surface was uniformly charged to -500V using a corotron 8, and the paper was supplied to the recording section at a speed of 200 mm/sec. In addition, an aluminum sleeve with an outer diameter of 32 mm is used as the non-magnetic sleeve 4, and the magnetic flux density on the sleeve is used as the permanent magnet 3.
A ferrite magnet magnetized with eight poles symmetrically at 800 Gauss was used, and only the permanent magnet 3 was rotated at 800 rpm. Then, magnetic toner with a thickness of about 1 mm (average particle size 20 μm, volume resistance 10 3 Ω-cm) is held on the sleeve, and the gap d is set to 0.9 mm, and the surface of the recording paper is rubbed while being rubbed. Spot diameter 0.05 from the back side
When an optical signal corresponding to the original image was irradiated with a semiconductor laser light beam of mm, a good inverted image with a resolution of 8 lines/mm was obtained. Note that in a normal copying machine, the moving speed of the recording paper is about 50 to 100 mm/sec, and according to the above example, a good reversed image was obtained even when moving at a fairly high speed of 200 mm/sec. .
