That is, it has been found that the paste layer 902 has elasticity with respect to humidity, and thus the mount 901 is likely to curl with a change in humidity, which significantly lowers transportability and may cause a jam or the like. .

The present invention has been made in view of the above problems, and an object of the present invention is to provide an image forming apparatus in which:
It is an object of the present invention to provide a pattern forming method and a pattern forming mount that can form a toner image on a paste layer of a mount without causing a conveyance failure.

[0006]

In order to achieve the above object, the invention of claim 1 provides an image forming apparatus on a layer of a pattern forming mount having a layer elastic to humidity. In the pattern forming method, a toner image is formed by using the toner image, and the toner image is burnt in a state of being superposed on the pattern forming target to form a pattern on the pattern forming target. As the above, the above-mentioned layer is formed on one surface of the mount, and a layer having elasticity to the same degree of humidity as that of the layer is formed on the other surface.

Further, the invention of claim 2 is a pattern forming mount having a layer elastic to humidity, wherein the layer is formed on one surface of the mount and the layer is formed on the other surface. It is characterized in that a layer having elasticity with respect to the same degree of humidity is formed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an example of a color copying machine which is an image forming apparatus to which the present invention can be applied will be described.
FIG. 1 is a schematic configuration diagram of a color copying apparatus, and FIG. 2 is an enlarged view around a photoconductor / intermediate transfer belt. A color image reading device (hereinafter, referred to as a color scanner) 1 forms an image of a document 3 on a color sensor 7 via an illumination lamp 4, a mirror group 5, and a lens 6 to obtain color image information of the document, for example, Each color separation light of blue (Blue, hereinafter B), green (Green, hereinafter G), and red (Red, hereinafter R) is read and converted into an electrical image signal. And B, G, obtained by this color scanner 1,
Based on the color separation image signal intensity level of R, a color conversion process is performed in an image processing unit (not shown), and black (hereinafter, referred to as Bk), cyan (Cyan, hereinafter referred to as C),
Magenta (hereinafter referred to as M), yellow (Yel
low, hereinafter referred to as Y). This is sent to a color image recording device (hereinafter referred to as a color printer) 2. The color printer 2 visualizes Bk, C, M, and Y based on this color image data.
A four-color full-color image is formed in the following manner from the toner image thus obtained.

The writing optical unit 8 of the color printer 2 converts the color image data from the color scanner 1 into an optical signal, performs optical writing corresponding to the original image, and electrostatically charges the photoconductor 9 (for example, OPC). A latent image is formed (for example, image portion (LD data “255” portion) -80
~ -130 (V), non-image part (LD data "0" part)-
500--700 (V)). The photoconductor 9 rotates counterclockwise as indicated by the arrow, and around it, a photoconductor cleaning unit (including a pre-cleaning static eliminator) 10, a static eliminator 11, a charger 12, a potential sensor 13, and a Bk developing unit 14. , C developing unit 15, M developing unit 1
6, a Y developing unit 17, an optical sensor 18 for detecting a development density pattern, an intermediate transfer belt 19, and the like are arranged.

Each developing unit has a developing sleeve (14a, 15a, 16a, 17a) which rotates by bringing a brush of the developer into contact with the surface of the photosensitive member 9 to develop the electrostatic latent image.
Developing paddle (14b, 15b, 16b, 17b) that rotates to pump and agitate developer, and toner concentration sensor for developer (14c, 15c, 16c, 17c)
It is composed of

Hereinafter, the outline of the copying operation will be described by taking the example of the developing operation order (color image forming order) as Bk, C, M and Y (however, the image forming order is not limited to this). . When the copying operation is started, reading of the Bk image data is started at a predetermined timing by the color scanner 1, and light writing by a laser beam and formation of a latent image are started based on the image data (hereinafter, electrostatic image formation by the Bk image data). The latent images are referred to as Bk latent images, and C, M, and Y are referred to as C latent images, M latent images, and Y latent images, respectively). Before the latent image front end reaches the developing position of the Bk developing unit 14 so that the front end of the Bk latent image can be developed, the developing sleeve 14a is started to rotate and the Bk latent image is developed with Bk toner. After that, the developing operation of the Bk latent image area is continued, and when the trailing edge of the latent image passes the Bk developing position, the developing operation is disabled. This is completed at least before the leading end of the C latent image based on the next C image data arrives.

The Bk toner image formed on the photoconductor 9 is transferred onto the surface of the intermediate transfer belt 19 which is driven at the same speed as the photoconductor (hereinafter, the toner image transfer from the photoconductor to the intermediate transfer belt is called belt transfer). ). The belt transfer is performed by applying a predetermined bias voltage to the transfer bias roller 20a while the photoconductor 9 and the intermediate transfer belt 19 are in contact with each other. It should be noted that, on the intermediate transfer belt 19, the Bk, C, M, and Y toner images sequentially formed on the photoconductor 9 are sequentially aligned on the same surface to form a belt transfer image of four-color superimposition. , Perform bulk transfer to transfer paper. This intermediate transfer belt unit will be described later.

On the side of the photosensitive member 9, the Bk process is followed by the C process, but the C image data reading by the color scanner 1 is started at a predetermined timing, and the C latent image is formed by writing laser light by the image data. The C developing unit 15 starts rotating the developing sleeve 15a after the trailing end of the previous Bk latent image has passed and before the leading end of the C latent image has reached the developing position, thereby developing the C latent image. Develop with C toner. After that, the development of the C latent image area is continued, and when the trailing edge of the latent image passes, the development is inoperable as in the case of the previous Bk developing unit. This is also completed before the leading end of the next M latent image arrives. In each of the steps M and Y, the operations of reading image data, forming a latent image, and developing are performed in the same manner as the steps Bk and C described above.

Next, the intermediate transfer belt unit will be described. The intermediate transfer belt 19 is stretched around a drive roller 21, a transfer bias roller 20a, a ground roller 20b, and a group of driven rollers, and is driven and controlled by a drive motor (not shown).

The belt cleaning unit 22 includes a brush roller 22a, a rubber blade 22b, a mechanism 22c for contacting and separating from the belt, and the like, and transfers the second, third, and fourth colors after the first color Bk image is transferred to the belt. During this operation, the belt is separated from the belt surface by the contact / separation mechanism 22c. Then, the four color images are accurately aligned on the intermediate transfer belt 19 and the images of the respective colors are transferred one after another to form a four color superimposed image on the intermediate transfer belt 19.

The paper transfer unit 23 includes a paper transfer bias roller 23a, a roller cleaning blade 23b,
And a mechanism 23c for contacting and separating from the belt. The bias roller 23a is normally separated from the surface of the belt 19, but the contact / separation mechanism 23c is arranged at a timing when the superimposed image of four colors formed on the surface of the intermediate transfer belt 19 is collectively transferred to the transfer paper. Pressed by the roller 2
A predetermined bias voltage is applied to 3a to perform transfer to paper. The transfer paper 24 is fed by the paper feed roller 25 and the registration roller 26 at the timing when the leading end of the four-color superimposed image on the intermediate transfer belt surface reaches the paper transfer position.

The transfer paper 24 on which the four-color superposed toner images have been collectively transferred from the surface of the intermediate transfer belt 19 is a paper transport unit 27.
Then, the toner image is conveyed to the fixing device 28, and the toner image is melted and fixed by the fixing roller 28a and the pressure roller 28b, which are controlled to a predetermined temperature, and is carried out to the copy tray 29 to obtain a full-color copy.

The photosensitive member 9 after the belt transfer has a photosensitive member cleaning unit 10 (pre-cleaning static eliminator 10).
a, the brush roller 10b, and the rubber blade 10c) are used to clean the surface, and the charge is uniformly removed by the charge removing lamp 11. After the transfer of the toner image onto the transfer paper 24, the surface of the intermediate transfer belt 19 is cleaned by pressing the cleaning unit 22 again by the contact / separation mechanism 22c.

At the time of repeat copying, the color scanner 1
The operation and the image formation on the photosensitive member 9 proceed to the second Bk (first color) image process at a predetermined timing after the first Y (fourth color) image process. In the intermediate transfer belt 19, the second Bk toner image is applied to the area where the surface is cleaned by the cleaning unit 22, following the batch transfer process of the first four-color superimposed image onto the transfer paper. The belt is transferred. After that, the operation is the same as that of the first sheet. The transfer paper cassettes 30, 31, 32,
Reference numeral 33 stores transfer papers of various sizes, which are fed and conveyed in the direction of the registration rollers 26 from the storage cassette of the size paper designated by the operation panel (not shown) at a certain timing. Reference numeral 34 denotes a manual paper feed tray for OHP paper and thick paper. The process speed is set to 180 mm / sec, for example.

The above is the description of the copy mode for obtaining four full colors, but in the case of the three-color copy mode and the two-color copy mode, the same operation as above is performed for the designated color and the number of times. It will be. In the single-color copy mode, until the predetermined number of sheets are finished, only the developing unit of that color is in the developing operation (agent standing) state, and the intermediate transfer belt 19 remains in contact with the surface of the photoreceptor 9. The copying operation is performed in a state where the belt cleaner 22 is driven at a constant speed in the forward direction and the belt cleaner 22 is also in contact with the belt 19. (Hereinafter, margin)

Here, a water-soluble glue layer 902 was formed on a mount 901 as a transfer body for forming a pattern on a transferred body such as ceramics, enameled glass, etc. by using the color copying apparatus having the above-mentioned structure. It is possible to form a design on the mount 500 with the glue layer.

It was easy to curl due to the difference in stretchability between 01 and the glue layer 902 with respect to humidity changes. On the other hand, in the present embodiment, by forming the glue layer 906 having elasticity similar to that of the glue layer 902 on the other surface of the mount 901, the acting force on the mount 901 is offset. Therefore, it is possible to prevent the curl of the mount 901 due to the change in humidity and improve the transportability. Further, in FIG. 4, the glue layer 9 having elasticity to the same degree of humidity is used.
02 and 906, a water-soluble adhesive material is used, for example, with the toner image forming surface facing the adhesive layer 902 side. As a result, the mount 901 and the resin layer with the toner image can be separated by immersing the transfer body on which the toner image and the resin layer are formed in water. Therefore, the pattern can be formed on the pattern forming object based on the steps of (d), (e) and (f) of FIG. 3 described above.

In the present embodiment, the two-component developing method that visualizes the electrostatic latent image is performed using the two-component developer containing the toner and the carrier, but the toner alone does not serve as the developer.
