CONSTITUTION:An air flow B is generated to transport forcibly ions generated by a corona discharger 8, and an electric signal is applied to a control electrode 7a to control the passing amount of ions. Recording device units 9a-9c of respective colors are arranged in series in the feed direction of the recording paper 6 and image signals 100a-100c of respective colors are applied to the respective units 9a-9c while giving a time difference based upon the delay of the recording paper 6, thereby forming the polychromatic image corresponding to the image signals 100a-100c on the recording paper 6. An air flow generation source 12 may be used in common and the polychromatic image recording device is reduced in size on the whole. Consequently, an image corresponding to electric signals is formed with the simple constitution, and the device is driven at the low signal voltage, and a high-reliability polychromatic recording device is obtained.

"Prior Art and Problems to be Solved by the Invention" A device that forms a powder image in response to an electric human power signal is a device that converts an electric signal to a light image and obtains a visible image using a normal electrophotographic process. There is also an electrostatic recording method in which a charging pattern is formed on the electrical body according to an electrical signal, and this is developed and transferred to form an image. A so-called contrast graph is known in which an electric field applying means such as a stylus electrode is provided, and powder is imprinted on a recording paper by the electric field formed by the electric field applying means to form a visible image.

Devices using electrophotography and electrostatic recording devices are recording devices that can obtain high-density, high-precision images, or require a drum or belt to carry a latent image, and require a process for forming and developing latent images. - Since it has many subsystems such as transfer, cleaning, and constant deposition, the equipment becomes larger and more expensive, and
There is a problem in that each subsystem requires high reliability.In particular, in multicolor recording, systems that include multiple latent image carriers, latent image forming means, and developing devices require an increase in the size of the device. Significantly, in a method in which latent image formation, development, and transfer are performed multiple times for each color on a single latent image carrier, the time required for image recording is longer than that for a single color, for the number of colors. There was a problem in that the recording speed was slow.

On the other hand, contrastography does not require a latent image and forms an image by directly transferring the toner on the developer carrier to the recording paper, so there are some drawbacks to latent image recording, such as no cleaning required. However, the size, size, and reliability of the device can be improved, and by using multiple developer carriers, multicolor recording can be easily performed with a small device.

However, since the configuration is such that an electric field is applied between the electric field applying means and the developer carrier via the recording paper, a high voltage is required to suppress the electric field required for the transfer of toner from the carrier to the recording paper. The problem was that it was difficult to drive electrically and ended up being expensive.

, this involves forming a thin toner layer on a carrier, applying a voltage to a multi-sided electrode provided close to the toner thin layer, selectively imparting an electric charge to the toner, and applying this electric charge to the toner. This device transfers only the toner that has been applied to the recording paper using a uniform electric field, and compared to the above-mentioned controllography, the applied electric signal requires a lower voltage, and since there is no paper in the signal application section, the electric field is reduced. The spread of the image is small, and the resolution is excellent.

The charge applying means used in the embodiments of the present invention is a charging means 4 based on ion flow modulation, and its characteristics are as follows:
As shown in the figure, it has a corona discharger (corona wire) 8 as an ion generating means and an airflow B for forcibly transporting the ions generated by the corona discharger 8, and is provided near the outlet of the airflow. By applying an electric signal to the control electrode 7a, the amount of ions passing through can be controlled. In addition,
Reference numeral 7b indicates a counter electrode. Note that H and V indicate applied high voltages.

In this method, since the applied voltage required at the control electrode 7a is sufficiently low, ranging from several to several tens of volts, a thin film driving element is incorporated into the charge applying means 4 itself, thereby reducing the size of the means and the entire device. It is possible to achieve this. In addition, since air flow is used as an aid for transporting ions, the charge utilization efficiency is lower than that of ion flow modulation means that does not have air flow.
This method is extremely superior in that it takes less time to apply the same amount of charge, making it possible to achieve higher speeds.

By applying a charge image-wise to one layer of the toner using the charge applying means 4, it is possible to eliminate the problem of contact charging due to multiple ↑1° electrodes and charging due to ion flow modulation without air flow, and to eliminate contamination of the electrodes. It can be completely avoided. Of course, there is no contact between the electrode and the toner layer, even if
Even if the toner 3 and foreign matter on the donor roll l are blown away by the ion flow, the charge applying means 4
Since the air flow is always flowing out from the control electrode 7a83, the toner 3 and foreign matter do not adhere to the electrode section or the exit section of the ion flow, which prevents the modulation of the ion flow and the influence on the toner. The charge is applied extremely stably.

The single layer of toner imagewise charged by the charge applying means 4 is then sent to the transfer section. In the transcription department,
With the transfer corotron 5 in close contact with the recording paper 6,
By applying an electric charge of the same polarity as the electric charge that the toner 3 has due to frictional charging from the back side of the recording paper 6,
It is possible to improve the recorded image by transferring only the image area toner whose charging polarity has been changed by the charge applying means 4 onto the recording paper 6 into the toner layer (Ft). Although electric charge is applied by the corotron 5 as an example, means such as a transfer roll or a transfer brush made of a conductive member and to which a voltage is applied may be used, and the present invention is not limited to a corona discharger.

This phenomenon often occurs when the toners 3 of each color have different polarities in triboelectric charging. This occurs when trying to transfer subsequent toner 3 with the same charging polarity as the toner 3 transferred onto the recording paper 6 first, and the toner 3 that is always transferred onto the recording paper 6 By performing the transfer with the opposite polarity, it is possible to prevent such toner 3 from being mixed in.
