イーが知られている。[Prior Art and Problems to be Solved by the Invention] A device for forming a powder image in response to an electrical input signal converts an electrical signal to an optical image and converts a visible image to i' using a normal electrophotographic process. - an electrostatic recording device that forms a charging pattern on a dielectric material according to an electric signal, and develops and transfers it to form an image; A so-called contrast technique is known in which an electric field applying means such as a Stites electrode is provided, and powder is deposited on a recording paper by the electric field generated by the electric field applying means to sieve a visible image.

を有する為に、装置の大型化、高価格化を生じると共に
、各サブシステムの高い信頼性を必要とするという問題
があった。Devices using electrophotography and electrostatic recording devices are recording devices that can obtain high-density, high-definition images, but they require a drum or belt to carry a latent image, and it is difficult to form a latent image. Since it has many subsystems such as - development, transfer, cleaning, and fixation, there are problems in that the apparatus becomes larger and more expensive, and each subsystem requires high reliability.
特に、多色記録においては、複数個の潜像担体、潜像形

形成、現像、転写を行う方式では、画像記録に要する時
間が、単色の場合に比べて色数分余分に必要であり、記
録速度の遅いものになるという問題があった。In particular, in multicolor recording, systems that include multiple latent image carriers, latent image formation stages, and developing devices significantly increase the size of the apparatus, and one latent image carrier can record multiple images for each color. The method of forming a latent image, developing, and transferring the image requires more time for the number of colors than in the case of a single color, and has the problem that the recording speed becomes slow.
一方、コントログラフイーにおいては、潜像を必要とせ

記録の欠点であったところの装置の大きさ、価格、信頼
性を改善する事が出来、複数個の現像剤担体を用いる方
式によって簡易に小型の装置で多色記録を行い得る。On the other hand, contrastography does not require a latent image and forms an image by transferring the toner on the developer carrier directly to the recording paper, so cleaning is not necessary, which is a disadvantage of electrostatic recording. However, the size, cost, and reliability of the device can be improved, and multicolor recording can be easily performed with a small device by using a plurality of developer carriers.
しかしながら、記録紙を介して電界印加手段と現像剤担
体間に電界を印加する構成であるため、トナーの担体か
ら記録紙への転移に要する電界を得る為には、高電圧を
必要とし、電気的駆動が難しく、結局高価格化してしま
うという問題があった。However, since the structure 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 obtain the electric field required for transferring the toner from the carrier to the recording paper. The problem was that it was difficult to drive the target, and the price ended up being high.
又、電界の広がりによって、解像力の限界が悪いという
欠点を有している。Furthermore, it has the disadvantage of poor resolution due to the spread of the electric field.
トナーを担体上に保持し、該トナーに画像状に選択的に
電荷を付与し、この電荷を付与したトナーのみを記録紙
へ静電的に転移せしめて画像を形成する方法も提案され
ている。A method has also been proposed in which an image is formed by holding toner on a carrier, selectively imparting a charge to the toner in an imagewise manner, and electrostatically transferring only the charged toner to recording paper. .

電界の広がりが少なく、解像力も侵れている。This forms a thin layer of toner on the carrier and the toner? :,
: Applying a signal to a multi-needle electrode provided close to the r layer,
It selectively charges the toner and transfers only the charged toner to the recording paper using a uniform electric field.
Compared to the above-mentioned controllography, the applied current signal only needs a low voltage, and since there is no paper in the signal application section, the spread of the electric field is small, and the resolution is also degraded.

べ低いとはいえ、百〜数百ボルトを要し、駆動素子の集
積化は困難であるという問題があった。However, in such a configuration, the multi-needle electrode needs to be in contact with or in close proximity to the toner,
For this reason, it was impossible to prevent the electrodes from becoming dirty, resulting in low reliability. Further, although the signal voltage is lower than that of controllography, it requires a hundred to several hundred volts, and there is a problem in that it is difficult to integrate the driving elements.
本発明は、かかる問題点にかんがみなされたものであっ

お、Ｈ１■、は、印加される高電圧を示す。The charge imparting 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) 6 which is an ion generating means, and an air flow B that forcibly transports the ions generated by the corona discharger 6. By applying an electric signal to the provided control electrode 7a, the amount of ions passing through can be controlled. Note that H1■ indicates the high voltage that is applied.

段に没れており、同一の電荷量を付与するのに要する時
間が短く、高速化を達成するものである。In this method, since the voltage required to be applied to the control electrode 7a is sufficiently low, ranging from several to several tens of volts, a thin film drive element is incorporated into the charge applying means 4 itself, thereby reducing the size of the coughing hand and the entire device. It is possible to achieve this goal. In addition, since air flow is used as an aid for transporting ions, the charge utilization efficiency is significantly lower than that of ion flow modulation means that does not have air flow, and it is difficult to apply the same amount of charge. The time required for the process is short and high speed is achieved.

電荷付与は極めて安定に行われる。By applying an image-wise charge to a single layer of toner using the charge applying means 4, it is possible to completely eliminate electrode contamination, which was a problem due to contact charging due to multi-needle electrodes and charging due to ion flow modulation without air flow. can be avoided. Of course, there is no contact between the electrode and the toner, and even if the toner 3 and foreign matter on the donor roll l are blown away by the ion flow, the control electrode 7a of the charge applying means Since the air flow is constantly flowing out, these scattered toners and foreign substances do not adhere to the electrode section or the exit section of the ion flow, and the modulation of the ion flow and the charging of the toner 3 are extremely stable. It will be held on.

好適である。In this embodiment, the intermediate transfer body 5 has a drum shape with a high resistance layer on a metal core, and a voltage having the same polarity as the charge that the toner 3 has due to triboelectric charging is applied thereto. The high resistance layer prevents the electric field between the donor roll 1 and the intermediate transfer body 5 from decreasing due to a large amount of charge flowing in one place when the donor roll 1 and the intermediate transfer body 5 come into contact. , a metal oxide layer or a resin layer in which conductive particles are dispersed are suitable.

。Using such an intermediate transfer body 5, a multicolor image is once formed on the intermediate transfer body 5, and then the multicolor image is transferred to the recording paper 10, so that the toner 3 is deposited directly on the recording paper 10, and the toner 3 is directly deposited on the recording paper 10. Compared to the conventional method, it is possible to obtain a clear and good multicolor image without causing misalignment of the positions of each color, that is, so-called color misregistration, which is likely to occur due to uneven conveyance of the recording paper 10.
