Abstract

PURPOSE:To transfer a displayed toner image by simple constitution by directly superposing it on recording paper after visually confirming the toner image formed on a display medium. CONSTITUTION:The film-like transparent display medium 2 comes in contact with a photosensitive body 1 where an electrostatic latent image is formed on its surface, and the toner image is formed on the display medium 2 by a developing device 7. The toner image is formed as a mirror image on a side opposite to a display part 15. The transparent display medium 2 on which the toner image is formed is fed to the display part 15, and displayed on the display part 15. At such a time, the displayed image is viewed as a normal image through the medium 2. The toner image displayed on the display part 15 is fed to a transfer and fixing means, and transferred and fixed on the recording paper 40 by selection by an operator. In such a case, since the toner image formed on the medium 2 is the mirror image, the image on the recording medium after transfer is the normal image. Therefore, both soft copy and hard copy are obtained by the simple constitution.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming method and an image forming apparatus using an electrophotographic recording system.

[0002]

2. Description of the Related Art Conventionally, as a display device, a CRT has been developed mainly for a television and has been widely used for displaying information on a personal computer and the like, but recently, a high-speed output function has been emphasized, and a liquid crystal display, a plasma display, etc. Devices are replacing this. However, it is difficult for any of the methods to perform large-capacity display and high-density display. Nowadays, with the diversification of information and the increase in the amount of information, there is an increasing need to display and confirm a large amount of information at one time without dividing it. In addition, a display device having high definition as in a normal hard copy is desired.

Therefore, a thermal display device and an electrophotographic display device have been proposed as satisfying the above two functions, that is, the large capacity and high density of the display function (see Japanese Patent Publication No. 61-30791). Japanese Patent Laid-Open No. 58-9874
(See Japanese Patent No. 6). In particular, an electrophotographic display device is expected to be excellent in display speed and high density as compared with a thermal display device.

In the above conventional electrophotographic display device, an endless display medium composed of a transparent film and a transparent conductive layer (for example, indium tin oxide thin film) and a photoconductive layer (for example, CdS) sequentially laminated on the transparent film. Is used. An exposure means is provided on the transparent film surface side of this display medium, and an electrical display signal is converted into light to perform optical writing on the display medium.

On the other hand, on the photoconductive layer side which is the opposite side,
A developing unit for forming a toner image to form a visible image is provided. Then, the display medium on which the toner image is simultaneously formed by the exposing unit and the developing unit is sent to the display unit so that the toner image can be directly viewed. Then, when the display content is modified, the display medium is moved and the toner image is removed by the developing means. Therefore, this developing means also serves as a cleaning means for removing the toner image previously developed at the same time as the development.

The display medium used in the above electrophotographic display device is formed by sequentially stacking a transparent conductive layer and a photoconductive layer on a film, and is very expensive. Therefore, an electrophotographic apparatus that does not use a conductive layer or a photoconductive layer as a display medium has been provided. FIG. 2 is a schematic configuration diagram of a conventional electrophotographic display device.

In the figure, reference numeral 1 denotes a photosensitive member formed in a drum shape, which is formed by providing a photoconductive layer on a conductive support and is rotated at a constant speed in the direction of arrow A by a motor (not shown). Reference numeral 2 denotes an endless display medium, and the display medium 2 includes the photoconductor 1, the rolling roller 3 and the pulling roller 4.
It is stretched over. Reference numeral 5 denotes a charging device as a charging means, which is provided so as to face the surface of the photoconductor 1. As the charging device 5, a corona charger as shown in the figure is generally used, but a brush charger or the like can also be used.

Reference numeral 6 denotes an exposure device as an exposure means, which converts an image electric signal into light and irradiates the photoconductor 1 with it. As the exposure device 6, in addition to the combination of the LED array used here and the SELFOC lens (trade name),
Any combination of a laser and an image forming optical system can be used. Reference numeral 7 denotes a developing device as a developing means, which is provided so as to face the display medium 2 and has a toner carrier 8
The toner 9 is adsorbed on the top and conveyed in the direction of arrow C,
Development is performed on the display medium 2 provided in close contact with the electrostatic latent image formed above.

Next, the operation and action of the electrophotographic display device having the above structure will be described. When the photoconductor 1 is rotated at a constant peripheral speed in the direction of arrow A by a driving unit (not shown), the display medium 2 moves in the direction of arrow B due to the frictional force with the photoconductor 1. Then, a tension mechanism (not shown) acts on the pulling roller 4 so that the display medium 2 moves at the same speed as the photoconductor 1, and an appropriate tension is applied to the display medium 2. And
The photoconductor 1 is uniformly charged by using the charging device 5.

Next, in the exposure process, the exposure device 6 irradiates the photoconductor 1 with light corresponding to an image signal to form an electrostatic latent image. In the developing process, development is performed by the developing device 7 provided in contact with the display medium 2 that is in close contact with the photoconductor 1. In this embodiment, reversal development is used, and a bias potential applying means is provided between the conductive support of the photoconductor 1 and the toner carrier 8 to apply the bias potential. As a result, the toner carrier 8 and the display medium 2
In the meantime, the lines of electric force associated with the electrostatic latent image formed on the photoconductor 1 penetrate the display medium and are generated. Then, the charged toner 9 on the toner carrier 8 adheres to the display medium 2 by electrostatic force and is developed to form a toner image.

The display medium 2 on which the toner image is formed subsequently moves to the display section. In this display section, the toner image formed on the display medium 2 can be visually observed through the glass 11. When the display content is changed, the display medium 2 is moved to the developing process again, and the toner image previously formed is removed by the developing device 7. On the other hand, the photoconductor 1 is separated from the display medium 2 after the developing process, and the entire surface is irradiated with light by the static elimination lamp 12 which is a static elimination means to remove the residual charges. In this way, the photoconductor 1 is repeatedly used.

In the development process, the previously formed history toner image on the display medium 2 is removed. At the same time, on the basis of the next electrostatic latent image formed on the photoconductor 1, the history toner image is formed on the display medium 2. A new toner image is developed. In the image forming apparatus having the above configuration, after visually confirming the toner image (soft copy) formed on the display medium 2 used for display,
The toner image may be copied (hard copy) onto a recording medium such as recording paper.

FIG. 3 is a schematic block diagram of an image forming apparatus having a hard copy function. In the figure, 16 is an intermediate transfer roller which is arranged to face the rolling roller 3 via the display medium 2, 17 is a recording paper, and 18 is a medium which faces the intermediate transfer roller 16 via the recording paper 17. It is a heating roller arranged. The toner of the toner image that has contributed to the display on the display unit 15 is once transferred to the intermediate transfer roller 16, then heated by the heating roller 18, melted, transferred again to the recording paper 17, and fixed.

[0014]

However, in the above-mentioned conventional image forming apparatus, when the toner image on the display medium 2 is directly transferred by superimposing it on the recording medium, it becomes a mirror image, so that the display medium 2 is provided downstream of the display unit. The intermediate transfer roller 16 which is an intermediate transfer medium is required to face the above. Therefore, not only does the structure become complicated and the image forming apparatus becomes large, but
Primary transfer and secondary transfer are required, which increases the number of transfer processes and deteriorates image quality.

The present invention solves the problems of the conventional image forming apparatus described above, and after visually confirming the image formed by the toner formed on the display medium, the displayed toner image is directly recorded on the recording paper with a simple structure. An object of the present invention is to provide an image forming method and an image forming apparatus capable of being transferred in an overlapping manner.

[0016]

Therefore, according to the present invention, in the image forming method of the present invention, a film-like transparent display medium is fed along the display portion, and the surface of the display medium opposite to the display portion is provided. That is, a mirror image toner image is formed on the back side of the display unit. The toner image displayed on the display unit can be transferred and fixed on the recording paper according to the operator's selection.

In the image forming apparatus for carrying out the above image forming method, a film-like transparent display medium, a display section for displaying an image so that an operator can visually recognize it, and the above display medium. Is provided along the display. Then, for example, an electrostatic latent image bearing member that is in contact with the display medium and forms an electrostatic latent image on the surface is provided, and a developing device is provided facing the electrostatic latent image bearing member with the display medium interposed therebetween. To be The developing device forms a mirror image toner image on the surface of the display medium opposite to the display portion, and the toner image is sent to the display portion and viewed by the operator as a normal image.

Further, a transfer / fixing means is provided downstream of the display portion in the feeding direction of the display medium, and the toner image formed on the display medium is selectively transferred and fixed.

[0019]

According to the present invention, the film-like transparent display medium as described above is brought into contact with, for example, an electrostatic latent image carrier having an electrostatic latent image formed on the surface thereof, and toner is applied to the display medium by the developing device. An image is formed. The toner image is formed as a mirror image on the side opposite to the display section. The transparent display medium on which the toner image is formed is sent to the display unit and displayed on the display unit.
At this time, the displayed image is viewed as a normal image through the transparent display medium.

The toner image displayed on the display unit is sent to the transfer / fixing means, and can be transferred and fixed on the recording paper according to the operator's selection. In this case, since the toner image formed on the display medium is a mirror image, the transferred image on the recording medium is a normal image.

Further, the surface 2b of the display medium 2 to which the toner adheres is coated with a fluororesin having good releasability. Further, in consideration of the lines of electric force generated between the display medium 2 and the toner carrier 8 in the developing process, the thickness of the display medium 2 is 100 μm or less, and
Considering the tensile strength and its handleability, it is desirable that the thickness be 5 μm.

Next, the operation and action of the electrophotographic display device having the above structure will be described. When the photoconductor 1 is rotated at a constant peripheral speed in the direction of arrow A in the figure by a driving unit (not shown), the display medium 2 is moved in the direction of arrow B by the frictional force with the photoconductor 1 and is wound around the winding roll 25. . At this time,

With such a configuration, the toner carrier 8 and the display medium 2 are
In this space, lines of electric force are generated by the electrostatic latent image formed on the photoconductor 1 by penetrating the display medium 2. Therefore, the charged toner 9 on the toner carrier 8 adheres to the surface 2b of the display medium 2 by the electrostatic force and is developed to form a toner image. Here, the above exposure process is performed so that a mirror image is formed when viewed from the surface 2b on which the toner adheres (see FIG. 4A).

The display medium 2 on which the toner image is formed sequentially moves to the display unit 15. In the display unit 15, the toner image formed on the surface 2b side of the display medium 2 can be visually observed through the glass 31 and the display medium 2. As described above, since the mirror image is formed on the surface 2b to which the toner adheres, the toner image becomes a normal image when viewed from the back side, the visual side (see FIG. 4B).

Next, when it is desired to make a hard copy of the displayed toner image, the halogen lamp of the heating roller 29 is first energized. At the same time, the recording paper 40 is taken out from the paper feeding means (not shown), conveyed to the paper feeding roll 45, detected by a paper sensor (not shown), and temporarily stopped. Then, when the temperature of the heating roller 29 reaches a predetermined temperature, the display medium 2

Immediately before or at the same time as the recording sheets 40 are stacked, the heating roller 29, which is a heating unit, is pressed against the drive roller 28. The heat of the heating roller 29 is transferred to the toner on the display medium 2 through the recording paper 40, and the toner is melted and transferred to the recording paper 40.

In the present embodiment, the melted toner is the recording paper 4
Penetrates to 0 and is fixed at the same time as transfer. Here, since the toner image is formed as a mirror image on the surface 2b side of the display medium 2 facing the recording paper 40, this toner image becomes a normal image when transferred to the recording paper 40 (FIG. 4C). reference). In this case, almost all the toner is transferred onto the recording paper 40 because the surface 2b of the display medium 2 to which the toner adheres is coated with a fluororesin having good releasability. Then, the display medium 2 is wound around the winding roll 25.

When hard copy is continued and the display medium 2 runs out on the supply roll 20 side, the drive roller 28 rotates in the direction opposite to the arrow D direction, the display medium 2 is returned to the supply roll 20 side, and is used again. To be done. On the other hand, when the hard copy of the displayed toner image is unnecessary, the drive roller 28 is rotated in the reverse direction to move the display medium 2 in the reverse direction in order to change the display content. Display medium 2 moved to development process
The previously formed toner image is removed by the rubbing force of the developing device 7. That is, the developing device 7 also has the previous toner cleaning function. A cleaning unit such as a blade may be provided to positively remove the toner.

FIG. 5 is a schematic view of an image forming apparatus showing a second embodiment of the present invention. In the figure, reference numeral 21 is an endless display medium stretched between the photoconductor 1 and the drive roller 28. A roller 32 for removing the slack of the display medium 21.
Is provided. In the image forming apparatus having the above configuration,
The toner image formed on the toner-attached surface 21b of the display medium 21 is sent to the display unit 15 and is viewed through the glass 31 and the two display media 21. When a hard copy is required, the recording paper 40 is manually fed from the upper insertion slot 32.

In the first and second embodiments, since the display media 2 and 21 on which the toner image is formed are visually observed by reflected light, it is possible to perform display with extremely strong contrast. Further, when the illumination in the room is weak and the displayed contents are difficult to see, an illumination lamp may be provided instead of the reflection plate 50 to illuminate and make it easier to see. For example, a plurality of fluorescent lamps and reflectors can be provided as illumination means on the back side of the display media 2 and 21 corresponding to the display unit 15. Thereby, the display media 2 and 21 on which the toner image is formed can be clearly seen. As a lighting means, a flat lighting lamp such as EL (Electro
Luminescence lamps and LED lamps can also be used.

The present invention is not limited to the above embodiments, and various modifications can be made based on the spirit of the present invention, and these modifications are not excluded from the scope of the present invention.
