CONSTITUTION:A color separating filter F1 where minute filters of filters B1 which permit only the blue light of three primary colors to transmit through, filters R1 which permit only the red light to transmit through, and filters G1 which permit only the green light to transmit through are combined in a form of mosaic is used, and the optical image of an original is exposed onto a photoreceptor 1 to form electrostatic latent images corresponding to respective color-separated images. Toner layers where toners TY, TC, and TM colored with complementary colors of blue, red, and green are stuck uniformly to surfaces of doners 41, 51, and 61 are charged with polarities opposite to those of latent images in accordance with respective color-separated patterns, and the photoreceptor 1 and respective donors are so rotated that corresponding color- departed latent images on the photoreceptor 1 are developed. Thus, a color image faithful to the original is obtained in a short time with one color separation.

Description

[Detailed description of the invention] The present invention relates to a color image recording method.

(Background of the Invention l Conventionally, a color image recording system for recording a color image in color uses the Karnun process. Electrophotographic systems such as Nonorar, etc., and three-color photoconductive f!1-particles vC'
Let's move the mood and color! It is a photoelectric dynamic color system that forms an image, and has a sensitivity for each of the three primary colors (C). °I know of a mosaic photoconductor type that uses a special photoconductor that is made from the enemy's former 2S city body elements in a mosaic IJ style.
I have 1z+.

However, in the color electrophotographic method using the above-mentioned Carlson process, the original σ) is used for each color separation.

Since it is necessary to repeat the Carlson process, there is a problem in that it takes a long time to record. Also.

In the photoelectrophoretic color system, it is difficult to produce sensitive photoconductive particles; processing of solutions is also difficult.

The problem with the Sarani and mosaic photoreceptor methods is that it is difficult to manufacture the mosaic photoreceptor itself.

(Objectives) Accordingly, the present invention is capable of color recording in a relatively short period of time and is easy to implement.

The object of the present invention is to provide a color image recording method.

(Structure) Color painting according to the present invention! The recording method is described below. It has three important steps:

These are a step of color-separating a color image to be recorded, a step of forming an electrostatic latent image corresponding to the color-separated image on a latent image carrier, and a step of developing the latent image to make it visible.

This is the process of separating color images.

This color separation is not performed sequentially using 23 types of filters for the three primary colors, but is performed one at a time using a unique color separation filter 2, and this is one of the features of the present invention. .

If the three primary colors are A, B, and C, this color separation filter has Ai! A minute A color light filter that transmits I light,
It is made up of a mosaic combination of minute color light filters that transmit B color light and minute C color light filters that transmit C color light.

The electrostatic latent image that corresponds to the combined separated image r that has been color-separated by such a special color separation filter.

A latent image is formed on the carrier.

As the latent image carrier, a photoconductive material or an electrically insulating material can be used. Various methods can be considered for forming electrostatic latent images.

For example, when using a photoconductive latent image carrier, the desired electrostatic latent image is created by uniformly charging the latent image forming surface and then irradiating it with a color-separated light image using a one-color separation filter. Alternatively, one color separation image can be converted into an electric signal, and a laser beam, for example, is intensity-modulated with this electric signal to write and scan a charged latent image carrier. A desired electrostatic latent image can be obtained by this method.

Note that when irradiating a single-color separated light image, the latent image carrier needs to have sensitivity to each color of A, B, and C light.

When the latent image carrier is electrically insulating.

The color separated image is first converted into an electrical signal, and this electrical signal is used to
For example, by driving a well-known multi-needle electrode to positionally selectively charge the latent image forming surface, the desired electrostatic image (a) can be obtained. Alternatively, an electrostatic latent image may be obtained on an electrically insulating latent image carrier by transferring the electrostatic latent image formed as described above onto a photoconductive latent image carrier. Good too.

To develop the electrostatic latent image formed in this way, 3
A seed toner is used. These three types of toner are powders and are colored in different colors. In other words, the toner of 1 loincloth is colored with α color, which is complementary to color A, the toner of 2 types of toner is colored with β color, which is complementary to color B, and the toner of 173 types is colored with color complementary to color 0. The color R is the same as the color R.

The three types of toner are 1--(,
Another thin layer of π-protection is applied uniformly to the peripheral surface of the donor 11b1. (In other words, the α color toner is uniformly thin layered.''
There is a retained donor, a toner having a thin layer of toner of the same color, and a toner having a thin layer of toner of γ color.

In the α color toner layer on the donor, a charge distribution corresponding to the A color light filter σ pattern in the color separation filter is formed by the electrostatic latent image and the polarity opposite to the electrostatic latent image. Due to the correspondence between this charge distribution, A color, and the optical filter distribution pattern, A color f
Color separation by filter and -2 [!41 image area can be developed in multiple layers.

Similarly, the layer of the I-color σJ) color corresponds to the arrangement i pattern of the eight-color light filter. Teiden distribution is formed,
On the toner layer of R, a bright cloth corresponding to the arrangement pattern of the C color light filter is formed.

With this first method, the color-separated image area formed by the B color vision filter VC can be selectively developed with β-color toner, and the color-separated image area formed by the C-color optical filter can be selectively developed with γ-color toner.

The color visible image obtained on the latent image carrier cannot be used for any purpose.

That is, if the latent image carrier is in the form of a sheet.

The latent image can be obtained directly on the carrier.

It can be fixed on a latent image carrier and used for recording,
Alternatively, it is generally possible to transfer and fix a color visible image onto an intermediate transfer medium such as a sheet of paper and use it for recording.

(Effects) In the color image distribution method according to the present invention, the color separation of the color image only needs to be performed once, so that the color image portion can be completed in a short time. Further, the color separation filter can be produced relatively easily, or a commercially available filter can be used, and a conventional method can be used as a means for forming an electrostatic latent image. Furthermore, a developing process has already been proposed by one applicant. You can also use the LIST distribution method. Therefore, the actual power of the present invention is extremely limited.

Although it is called a micro filter, its individual shape is 11.
There are various types. Another way to combine minute filters in a mosaic pattern is to combine tiny hexagonal filters in a tortoiseshell pattern. , the longitudinal direction of the filter F1, etc., the direction of the symbol l is called the IIG direction.

Now, as an example of a device for carrying out the present invention, the present inventor prototyped a device whose essential parts are schematically shown in Figure 2.

In the figure, numeral 1 is a photoconductive photoreceptor as a latent image carrier, numeral 2 is a charger, numeral 3 is a slit plate, and numeral 4 is

It clearly shows the recording paper used as a photographic medium, and the transfer charger 1-11 & 2.

f'f Each light body is placed on a 120-meter beam drum with toe rM*74℃, Te: 10 W%
Gold-containing Se-Te combination 1>? Thickness: 45μmK
It is made by vacuum deposition and can be rotated in the direction of the arrow. This photoreceptor 1 has a ζ1 panchromatic sensitivity. Therefore, we are sensitive to red light, blue light, and green light.

As shown in Figure 1, a charger 2.
Slit plate 3. Momo image fM, -4.5, 6. Middle school 1iii
Enemy photo 7. Static eliminator8. In addition, a horizontal stripe with a stripe width of 100 μm, filter FL, was installed between the photoreceptor 1 and the slit plate as a one-color separation filter. It was brought back to life and deployed. In the figure, the width direction of the filter Fi0 is drawn. Therefore, the longitudinal direction of the filter F1, that is, the longitudinal direction of the microfilter is
It is parallel to the zero rotation axis direction and perpendicular to the drawing.

The developing devices 4, 5.6 are structurally equivalent to each other, and the difficulty is that the LI proposed by the applicant
ST I don't know about μ in relation to the recording method. Now, we will take rice grains and image b''4 as a representative example, and briefly explain their structure and function.

The main parts of the developing device 4 include a donor 41, a hopper 42, a blade 43, and a multi-needle electrode 44.

The donor 41 is roller-shaped, and its surface is.

Covered by a thin silicone rubber layer. This donor 4
1 is a rotary axis in the direction of the arrow, and its axis of rotation is parallel to the rotation axis of the photoreceptor l, VCl, and its circumferential surface is 1.
Over the rotation axis surface. , is brought into light contact with the circumferential surface of the photoreceptor.

A pumper 42 disposed above the donor 41 stores yellow toner TY, and supplies the toner to the upper peripheral surface of the donor 41 from a supply port. When the donor 41 is rotated in the direction of the arrow, the toner TY that has not been supplied moves together with the peripheral surface of the donor 41σ), and the doctor blade 4 disposed in the internal recess of the left side wall of the hopper 42σ) moves. From K, a uniform thin layer of toner 4l-Fr, toner Yoi'' or J1
? I will do it.

Plate 4: 3 is tetraelectric and 1 direct MC (not shown)
The toner TYK is drawn into a pressure II bowl, and through the plate 43, a positive charge is injected into the toner TYK.

Therefore, the thin layer of toner TY' formed on the donor 41 by the blade 43 is uniformly positively charged.

The multi-needle electrode 44 is in the form of a thin plate whose longitudinal direction is perpendicular to the drawing, and has one end edge K&a that extends in the longitudinal direction.
r: A large number of embedded needle electrodes are neatly arranged in the longitudinal direction of the minute end surfaces.

This end surface is brought into contact with the toner TY layer on the toner 41.

A pulsed stationary pressure signal is applied to this multi-needle electrode at a constant frequency.
when the signal is applied.

The toner TY in contact with the end surface of the needle electrode is reversely charged. By one signal, the toner TY on the donor 41 is charged in the form of a narrow strip vc@ whose longitudinal direction is perpendicular to one drawing. Since the signal is applied at regular intervals, the position of the multi-needle electrode 44 can be adjusted evenly.
The positively charged portions and the negatively charged portions are arranged alternately in a striped pattern. This σ) and the distribution of the negatively charged charger, that is, the charge distribution of negative 4 to 8 charges, are measured using a 5-color separation filter Fl.
, 11I! ' The arrangement pattern of the color filters Bl is made to correspond to the arrangement pattern of the color filters Bl.

Similarly, on the donor 51 in the developing device 5.

In the layer of cyan toner TC, a charge distribution corresponding to the 7+1 pattern of the red filter R1 in the filter FIK is formed, and the donor 61 in the developing device 6 is
Above, the magenta toner TM layer K&'! , to form a charge distribution corresponding to the arrangement pattern of the green filter G1 in the filter FIK.

The intermediate transfer medium 7 is in the form of a roller, and the circumferential surface of the metal roller is covered with a thin electrically insulating layer so that the cylindrical surface of the intermediate transfer medium 7 is aligned with the rotation axis perpendicular to the drawing. , is brought into light contact with the circumferential surface of the photoreceptor 1 in the direction of the rotation axis. In addition, this intermediate transfer medium 70 gold maple roller is supplied with a direct Mt power supply (not shown) as W: Yoichi F1: n-, by.
A bottom pressure of t'l is applied.

For color double-image recording, while rotating the light body 1 in the direction of the arrow at 1.1, the charger 2 uniformly wraps its circumferential surface by 11 inches, and at the position of the slit shell 3, the filter 7F
irradiate the color original light f image through
IyI and Fukumitsu at the same time t1. ．． ! If row t [I, the obtained electrostatic latent image is developed 111 times by the development method 4, 5.6, and the colored visible image formed on the photoreceptor l is ", eaves-" on the recording paper 10 through the photographic medium 7
Electrostatic transfer is performed using a thick YARJAR 11, the transfer wave is removed by an alternating current corona using a static eliminator 8, and then the transfer wave is removed by an AC corona using a static eliminator 8.

2 Cleaning is carried out using leaning equipment 9 → 111. The transfer onto the recording paper 10 by the transfer charger 11VC is as slow as possible. The color visible image/gap transferred onto the 6-layer recording paper 10 is fixed on the 1-layer recording paper 10 by the 1.7th fixed viewing pupil shown in FIG. As the exposure system in which the photoreceptor 1 is placed at the tip, a slit exposure type system was used which can project a normal image of a color original onto the photoreceptor 1.

Below, the process of forming an electrostatic latent image, following the formation of an electrostatic latent image and warping, will be explained with reference to Figure 3).

In FIG. A.3, reference numeral 1 schematically indicates a photoreceptor 1. As shown in FIG. Reference numeral 11 indicates an aluminum drum as a conductive substrate, and reference numeral 12 indicates a photoconductive layer. That is, in FIG. 313, the drum-shaped photoreceptor 1 is expanded in a plane and turned upside down as an explanatory diagram. In the figure, the right direction corresponds to the (b) rotation direction of the photoreceptor 1 in Figure 311 π←j.

Figure 3 (1) shows a state in which the photoreceptor 1 is uniformly positively charged by the charger 2.

In this state, one image is produced using four lights. This state is shown in Figure A.3 (If). Image exposure is performed by projecting the optical image of color original 0 onto photoreceptor l via filter F1. Assume that a document O has a black part N, a white part W%, a red part R1, a blue back part.

In the filter Fl, a blue light filter, -B
l, red light filter old, green light filter G1
are lined up with stripe width. In other words, in Figure 5, the horizontal direction is the width direction of the filter F1.
respond.

Now, when the optical image of the original O is projected onto the photoreceptor IK, <
, also, if filter F1 is tf, ) shore + high 0
The parts corresponding to the white part W and Akato R1 blue back part are.

Fidget #1. Is it illuminated with white light, red light, blue light?
In reality, there is a filter Fl, a W color light filter 7 Bl and a green light filter G1 function as photoreceptors for red light, and a red color light filter R1,
Green light filter 01 is for blue light.

Since the filter functions as a shield, only the portion corresponding to the red light filters R1 and K is exposed in the portion corresponding to the red part of the original Oσ). The back of the casing corresponds to B, and the light filter B1 is connected to the photoreceptor L (1'3 1 (1) vc.
An electrostatic foil image is formed as shown.

At this time, the light image that is not struck onto the photoreceptor 1 via the filter F1 is a color-separated image, and the electrostatic latent image that is formed corresponds to this color-separated image. ing.

The electrostatic latent image thus formed is - first.

The developing device 4 develops using yellow toner TY. This state is shown in Figure 3 (III). The donor 41 in the developing device 4 is also developed in a plane, and the right direction in FIG. 1 corresponds to the first direction of rotation of the donor 41.

In the thin layer of toner TY on the donor 41, a charge distribution is formed by positively charged and negatively charged toners as described above, and this charge distribution is expressed in Figure 1 as described below. has been done. That is, as shown in Figure 3'3 (1), the toner TY that has been subjected to cross-cutting is negatively charged, and the toner TY that has been subjected to hatching is positively charged. Consider that the charges that make up the electrostatic latent image are of positive polarity.

Of the toner 'ry on the donor 41, the negative electrode 8: VC
It is easy to understand that only those that have the ability to develop electrostatic latent images have the ability to develop electrostatic latent images. Of the toner TY, the one that is electrified is linearly distributed in one direction perpendicularly to one drawing.
In comparison with Figure 3 (1) K ii tr filter F1, we can see that the distribution of charged toner TY is different from that of filter FIK and a) g color light filter B1 σ
) It will be seen that the configuration is consistent with the configuration ghatern. Toner TY's colors have a wide range of colors, and there are gNVCs between the colors and complementary colors. One layer of toner on the donor is filtered with a color complementary to the toner color σ) One color separation -
Forming a charge distribution corresponding to the distribution pattern in the filter means 5σ).

Now, if we do this, of the electrostatic charge lh1ψ on the photoreceptor 1, the part corresponding to the image part whose color has not been separated by the blue light filter in the filter Fl Although it is called a decomposed image part, only this Bi1 decomposed image part is selectively subjected to fV.

Similarly, the distribution of the toner TCK on the donor 51 of the historical image storage 5 is the same as the arrangement pattern of the red light filter R1 in the filter FIK. We are doing so. Toner without hatching has no developing ability, so in this developing device 5.

The color-separated image area by the red light filter RIK is visualized by the cyan toner TCK.

Similarly, in the developing device 6. Donor 61 σ) Magenta Toner TM K. The distribution of the negatively charged toner (hatched) matches the arrangement pattern of the green light filter G1 in the filter FIK, and in this developing device 6, the color by the green light filter in the electrostatic latent image is Only the resolved image platform is visualized with Magenta Toner™.

In this way, a color 〇Tib image is formed on the photoreceptor 1. In this visible image, three types of toner, yellow, cyan, and magenta, are arranged alternately with a stripe width in the part corresponding to the black part NVc in the original OK, but since the stripe width is as small as 0.1 mm, The visible image as a whole appears black. Similarly, the portion corresponding to the red portion R in the original O is yellow toner TY and magenta toner T.
M turns off the uniformity of the clothes, and lt part B uses magenta toner T.
It is expressed by M, cyan toner TC, and f.

In this way, [qt+color〇[
As mentioned above, the intermediate transfer medium 7 (Figures 1 and 2) Through the process, 8 Pirokuo Mr. 10 was transferred, and furthermore, this Hiroku water (
:The first one fixed on H1.

In ζ% homogeneous image N% 4.5.6, the charge distribution and color separation il that quickly develops the color separation image stage 1- by each color light filter! Is it necessary to perform accurate alignment with the II image section?

Therefore, we installed one encoder in the side direction of the color document placement area.
! ! While slit-cutting the original, the above encoder was picked up by a decoder to detect the timing of surin 1 scanning, and the above-mentioned alignment was confirmed by kneading.

The peripheral speed of the photoreceptor l and the linear speed of the medium 1141 transfer medium are set to 10
When I experimented with 0 Ryu/see, I was able to get a good Kara A Piroku-11 mound, but this D Viroku it! When looking closely at the n-image, no stripe structure due to each toner was observed.

Therefore, as the first filter F1, a horizontal stripe filter with a stripe width of 0.1 mm and the same size as the original is placed in close contact with the original surface, and a cylindrical lens is combined with the imaging optical system. The exposure light image of one document is enlarged three times only in the direction of movement of the circumference 1h1 due to the rotation of the photoreceptor 1, and the circumferential speed of the photoreceptor is increased to 300 mtx /
image exposure is carried out as the development device 4.
The toner layer on each donor in 5.6 has a width of 0.3 mm for the negatively charged toner and a width of 0.3 mm for the positively charged toner, corresponding to the arrangement pattern of the light filter in the color separation filter. 0.6 to form a charge distribution,
On the other hand, the peripheral speed of the intermediate transfer medium 7 is set to 10 Oram/see, and the color visible image, which has been stretched three times in the direction of rotation of the photoreceptor, is transferred to 1. Only the direction corresponding to the stretched direction is transferred onto the intermediate transfer medium by pressing 1/3, and in this way,
The visible image that has returned to its normal size is transferred onto the recording paper 10.

Once established, the striped structure is not good, it's a good guy.
I was able to obtain a record image.

Note that when color separation is performed using a horizontal stripe filter, a two-blade electrode is used instead of the multi-needle electrode in the developing device, that is, a thin metal blade plate is used instead of the needle electrode, and one plate is used for this stripe filter. It is possible to use one in which the edge portion is used as an electrode.

t [Oh, when forming an electrostatic latent image, set the photoreceptor 1 to +8
After charging to 00VK, one image exposure was performed.

Also in the charge distribution on the donor of the 1st generation imager.

The amount of positive and negative charging, Tonate, is ±20 μc/g.

Next, in Figure 2, for filter F1,
・Experiments were conducted using the vertical stripe filter F2 shown in Figure 1. The stripe width of the filter F2 used was 0.1 degrees.

Stripe filter F2 0>Longitudinal direction is mochi/)
Yes, it is parallel to the direction of the rotation axis of the photoreceptor 10. In this case, the above explanation applies to the color separation one-image exposure and development, provided that the left and right direction in FIG. 6 is considered to be the rotational axis direction of the photoreceptor 1 and each donor. 1. In this case, in the longitudinal direction of each color light filter in the color separation filter and in the charge distribution of the toner on the donor. Since the direction of the linear arrangement of the negatively charged toner is parallel to the moving direction of the circumferential surface of the photoreceptor l, it is easy to align the one-color separation image area and the distribution of the negatively charged toner for developing the image. be.

By making the peripheral speed of the donor faster than the one-peripheral speed of the photoreceptor 1, it is possible to obtain a color recorded image K:TV: by increasing the image density and reducing background smudges. confirmed.

In addition, in order to negatively charge the toner, color recording images can be produced by changing the shape of the signal voltage, such as changing the signal voltage applied to the multi-needle electrode from a pulse waveform to an AC waveform or a parabolic waveform. It was also possible to improve the image quality.・Also, as a single color separation filter,〕・1
Figure θ) Filter F1 KInstead, we used the dot-shaped filter F3 shown in Figure 3.1. When we recorded the donor-like charge distribution corresponding to the dot-type, we found that good quality was obtained by the net size table. I was able to obtain a color image.

In addition, a filter equivalent to filter F1 and the like and having the same size as the original was brought into close contact with the surface of the original to carry out color separation, and the color-separated image was converted into electrical signals.

This electric signal was used to modulate the intensity by 1 to make it 5. A laser printer is used for image calculation.

A charge distribution corresponding to the weight resistance pattern of each color light filter in the filter was formed and recorded on each donor, and similarly, good color recorded images were obtained.

Also, instead of using a laser printer.

An electrostatic latent image may also be formed by using a multi-needle electric motor and applying the above electric signal to the multi-needle electrode.

A good color recorded image could be obtained. An electrostatic latent image is formed using a multi-needle electrode. In such cases.

The latent image carrier does not need to be a photoconductive film, and an electrically insulating latent image carrier may be used in place of the photoreceptor.

In addition, a filter F3 was used, and in addition to the 4° 5.6-inch image center, another one of the same type was added, and black toner was used in this developing device.

When a black image area was manually specified in the original document placement section and this black image area was developed using only black toner, it was possible to obtain an image quality equivalent to that of the black and white copy W1w.

Note that by changing the negative charge 1 of the toner on each donor, it was possible to adjust the color balance ch A.

Finally, on the photoreceptor 1, there is a filter FIK. This photoreceptor was formed by directly overcoating it with a single layer of filter (based on dielectric material) with a thickness of 10 μm.

It is negatively charged (discharge voltage -7,0KV) and becomes
in.

Recording was carried out by forming an electrostatic latent image using a so-called polarity reversal electrophotographic method in which image exposure was performed after positive charging at a discharge voltage of +5.7 KV.

Similar to the initial results above, good results were obtained.

In the case of the present invention, the electrostatic latent image formed on the latent image carrier can be used repeatedly until the warp is attenuated. In the example device shown in FIG.

In an experiment conducted with the static eliminator 8 and cleaning device 9 inactive, 20 good color images were recorded.
