2. Description of the Related Art Recently, OA (Office Automation) has made it possible to record information on recording paper by a printer, a copying machine, or the like. A large amount of paper is generated, but at present, most of the paper is wasted.

[0003] Disposal of paper on which such information is recorded requires a great deal of cost, and also degrades the local environment due to the disposal, and consequently reduces the global environment due to deforestation for producing paper. Leads to deterioration.

Heretofore, in order to solve this problem and to recycle paper, measures have been taken to remove used ink on the paper once used, soak and re-use it, and use it as recycled waste paper.

[0005] In the process of recycling used paper, a large-scale used paper recycling facility is required.
A number of processes had to be taken, such as sorting, collection, and transportation, to obtain recycled paper.

A recording material reproducing method for removing the image forming substance from the recording material on which the image is formed and reproducing the recording material (Japanese Patent Laid-Open Publication No.
No. 152731 and JP-A-7-13383) and a copy or recorded image support at least partially composed of a paper layer, having a density of 0.1 to 100% by weight.
Surfactant aqueous solution or surfactant at a concentration of 0.1 to 6
After applying an extremely small amount of a 0% by weight aqueous solution of a water-soluble polymer or an aqueous solution of a mixture thereof, the image support and the image release body are heated and pressed to contact and dried to produce a copy or recorded image exclusively for recycling. A method of manufacturing a forming support has been proposed (see Japanese Patent Application Laid-Open No. 8-152773).

[0007] These methods for reproducing a recording material and for manufacturing a support for exclusive use for recycling or copying or recording image formation use a liquid such as a pretreatment liquid when removing an image forming substance from a recording medium. It can be said that the method.

Conventionally, various recording media have been proposed in which the image forming substance is removed by a dry method using no liquid instead of the wet method.

For example, a printed material (for example, see Japanese Patent Application Laid-Open No. 2-55195) in which, for example, a silicon-based release material is applied on a support, a liquid composition containing a curable silicon compound is applied to a substrate, and then dried. A silicone compound and fine particles are contained on an image recording medium (see Japanese Patent Application Laid-Open No. 9-204060) having a film formed thereon and a substrate mainly composed of pulp fibers, each of which can be bonded by a chemical reaction. Image recording papers having a recording surface comprising a coating obtained by applying or impregnating and drying a liquid composition comprising a silicone compound (see Japanese Patent Application Laid-Open No. 9-204061) have been proposed.

[0010]

That is, the techniques described in JP-A-8-152731, JP-A-7-13383 and JP-A-8-152731 can be applied to a wide range of recording materials (recording media). When removing the image forming substance, a liquid such as a pretreatment liquid is applied to the recording medium, and
Means for drying the recording medium coated with the pretreatment liquid is required, which increases the size of the apparatus and increases the cost.In addition, since the liquid is applied, depending on the type of the recording medium, wrinkles, waving, and There is a possibility that elongation or the like may occur, and there is a demand for downsizing and lowering the price of the device.There is still room for improvement, and wrinkles and wrinkles are required to improve the reusability of the recording medium more appropriately.

[0024]

According to the recording medium of the present invention, a predetermined coating layer is formed on a surface of a predetermined base material, and an image is formed on the surface of the coating layer by a predetermined image forming substance. Then, when pressure is applied at a predetermined temperature in a state where the surface on which the image is formed is in close contact with a predetermined peeling member, the image forming substance is transferred / removed to the peeling member and is a reproducible recording medium. The above-mentioned object is attained by forming the coat layer from a material having a predetermined releasability and a predetermined compatibility with the image forming substance.

Here, the recording medium has a coat layer formed on the surface of a base material, and the base material may be paper or a plastic film as described later.

The coating layer is required to have good releasability from an image forming substance formed on the recording medium in order to improve the reusability of the recording medium and improve the image quality. Good compatibility with the forming material is required.

As the material for the coating layer, first, from the viewpoint of releasability, a resin containing fluorine is suitable as described later. Examples of the resin containing fluorine include, for example, PFA (tetrafluoroethylene / porfluoroalkylvinyl ether copolymer, critical surface tension 17.8 mN / m) used as a surface release agent for the fixing roller of an electrophotographic image forming apparatus, and an intermediate transfer belt of an image forming apparatus ETFE used as
(Ethylene / tetrafluoroethylene copolymer, critical surface tension 22.0 mN / m). These materials are
It has material properties such that toner as an image forming substance does not adhere or toner adheres but does not adhere, and is suitable as a coat layer. Further, silicon-based oil used for releasing the surface of the fixing roller is also a material having good releasability, and is suitable as a coat layer.
Further, as the coating layer, in addition to such a fluorine-containing resin or silicone-based oil, it is possible to use a certain surfactant or a substance having a numerical value that is different in surface energy from an image forming substance. it can. That is, the critical surface tension of a general toner as an image forming substance is 32 to 3
Since it is 3 mN / m, the further away from this value, the lower the fixability, and conversely, the releasability improves.

As described above, the recording medium includes:
In order to improve the image quality, it is also required that the image formed on the recording medium has good fixability and storage stability. That is, when a recording medium on which an image is recorded is handled in an overlapping manner, or when the image forming substance on the recording medium is transferred to another recording medium on which the image is recorded, or when the image is smeared when touched by a hand. This is because if the dropout occurs, the image quality is degraded and cannot play a role as a recording medium.

The fixing property of the image forming substance can be ensured by giving the image forming substance and the surface of the recording medium, that is, the coating layer, mutual compatibility so that they can shift to an adhesive state. Having the compatibility means that the plasticizer is homogeneously mixed with the polymer substance without causing phase separation, and the material of the coating layer of the recording medium has such properties with respect to the image forming substance. When it is provided, the fixing property of the image forming substance can be secured.

However, under the condition that the image forming substance and the coating layer are actually dissolved during image formation and reproduction, the image forming substance on the recording medium is appropriately removed,
Since it becomes difficult to reproduce, as described later, the recording medium is heated to a temperature equal to or higher than the softening point of the image forming substance and lower than the thermal deformation temperature of the material of the coat layer. The recording medium and the peeling member are pressed with a pressure lower than the heat deformation pressure.

Examples of the material of the coating layer having the characteristics of the release property and the compatibility include, for example, PVDF.
(Polyvinylidene fluoride, critical surface tension 25 mn /
m) or a copolymer of PVDF and another polymer.

Since this PVDF is a family of fluororesins, it is basically an inactive resin and has a generally known releasability. Therefore, PVDF is:
It has poor adhesiveness and has a property of easily peeling or transferring an image forming substance. On the other hand, PVDF is known to have compatibility with acrylic resins and vinyl acetate resins (see “Fluorine Resin Handbook”, published by Nikkan Kogyo Shimbun, 1991.11.30, p. 394). Also,
Saturated polyester is known as a plasticizer for PVDF, and it is known that it has a large plasticizing effect and good compatibility (“Polymer modification technology blending and processing”).
Chemical Industry Co., Ltd. Published December 1, 1979, P1
52).

In general, examples of the binder resin of the image forming substance used in the image forming apparatus include the following. Examples of the binder resin for heat fixing include polystyrene, styrene-acrylic resin, polyester resin, epoxy resin, vinyl butyral resin, polyamide resin, and polyolefin, and further, for pressure fixing, polyethylene, ethylene-vinyl acetate resin, Wax-like rubbery resins such as styrene-butadiene rubber can be mentioned. Above all, styrene
Acrylic (esterified state of acrylic acid) resin is particularly frequently used, followed by polyester resin. However, a styrene-acrylic resin may be contained in the polyester resin binder in some cases (see JP-A-5-27478 and JP-A-9-43899).

Among the image forming substances, those formed of the above-mentioned styrene-acrylic resin and those formed of a polyester-based binder resin containing the styrene-acrylic resin show compatibility with PVDF, It has sufficient fixability as a coat layer of a recording medium.

Further, a polyester toner comprising only a polyester resin binder containing no styrene-acrylic resin has an affinity for PVDF, and is sufficiently fixed to a recording medium when an image is formed by an image forming apparatus. It has nature. That is, PVDF is a highly polar resin among fluororesins, and has the same ester bond as a compatible acrylic resin, vinyl acetate, and a saturated polyester which is a plasticizer of PVDF. It has an affinity for the polyester-based toner which is a substance and is suitable as a coat layer of a recording medium.

An image is formed on the recording medium by an electrophotographic method using dry toner.

According to the above construction, the recording medium has a coating layer formed on the surface of the base material from a material having a predetermined releasability and a predetermined compatibility with a predetermined image forming substance, At the time of reproduction, when pressure is applied at a predetermined temperature in a state where the surface on which an image is formed is in close contact with a predetermined release member, the image forming substance is transferred / removed to the release member so that the image can be reproduced. While improving the fixability of the image forming substance to the recording medium by the forming apparatus, the transfer / removal performance of the image forming substance to the release member can be improved, and good image quality can be ensured. ,
The reusability of the recording medium can be improved.

In the intermediate recording medium according to the second aspect of the present invention, a predetermined coating layer is formed on the surface of a predetermined base material, and a mirror-reversed image is formed on the surface of the coating layer by a predetermined image forming substance. Then, when pressure is applied at a predetermined temperature while the surface on which the image is formed is in close contact with a predetermined member to be transferred, the image forming substance is transferred to the member to be transferred, and the image is transferred to the member to be transferred. An intermediate recording medium that can be transferred and formed on a transfer member and from which the image forming substance is removed and reused, wherein the coating layer has a predetermined release property and a predetermined compatibility with the image forming substance. The above object is achieved by being formed of a material having a combination of the above.

Here, the member to be transferred is a decorative plate, a porcelain plate, a metal plate, a wallpaper, a paper that cannot be set in the image forming apparatus, a wooden plate,
An image forming apparatus such as a tile plate or a plastic plate cannot directly form an image. A mirror-reversed image formed on an intermediate recording medium is transferred to such a member, and an image in a correct direction is formed. Is formed on the member to be transferred.

According to the above construction, the intermediate recording medium is formed on the surface of the base material with a predetermined coating layer formed of a material having a predetermined release property and a predetermined compatibility with a predetermined image forming substance. During transfer, if the surface on which the image is formed is in close contact with a predetermined member to be transferred and is pressed at a predetermined temperature, the image forming substance is transferred to the member to be transferred, and the image is transferred to the member to be transferred. Since the image forming substance is removed and reusable while being transferred and formed on the transfer member, the fixing property of the image forming substance onto the intermediate recording medium by the image forming apparatus is improved, and the image forming substance is transferred to the member to be transferred. The transfer performance of the image forming substance can be improved, good image quality can be ensured, and the reusability of the intermediate recording medium can be improved.

In each of the above cases, for example, the material of the coating layer may be polyvinylidene fluoride or a copolymer of vinylidene fluoride and another polymer. .

According to the above construction, since the coating layer is formed of polyvinylidene fluoride or a copolymer of vinylidene fluoride and another polymer, it is most often used in a general image forming apparatus. It has good releasability to colorants other than styrene-acrylic image forming substances and binder resins, and can improve transfer performance to a peeling member and a member to be transferred, and has good fixation. , The image quality can be maintained, good image quality can be ensured, and the reusability of the recording medium and the intermediate recording medium can be improved.

Further, for example, as described in claim 4, the coat layer may be formed of the material in an amount of 50 g / m ² or less.

Here, if the material of the coat layer is 50 g / m ² or less, the coat layer and the base material can be used even after the recording material is repeatedly reused due to the linear expansion coefficient or the thermal expansion coefficient of the base material. Are not separated from each other, and the texture of the substrate is not significantly impaired. In addition, as a lower limit of the amount of the material of the coat layer, according to the results of experiments conducted by the present applicant, when the base material is paper, an application amount of about 2 g / m ² covers irregularities of the paper. Therefore, the above-mentioned about 5 g / m ² is the lower limit value because there is a possibility that the image forming substance may be left behind.
That is, when the base material is paper, the material of the coat layer is about 2 g /
When the coating amount is m ² , the residual image density after removing the image is an OD value (measured optical reflection density) of as high as 0.50, and a problem that the image of the original character or the like is recognized is observed. However, when the coating amount of the material of the coat layer is about 5 g / m ² or more, the OD value can be suppressed by at least one digit from 0.02 to 0.04, and the original image is not recognized. Image removal quality can be ensured. When the substrate is a plastic film, the amount of the material of the coat layer is about 2
Even at a coating amount of g / m ² , there was no residue of the image forming substance, and the image was completely transferred.

According to the above configuration, the coating layer is coated at 50 g /
Since m ² is formed in the following amounts of materials, without compromising the characteristics of the substrate, while the fixability of the image forming substance on the recording medium by the image forming apparatus can be favorable, the peeling member and the transfer member It is possible to improve the transfer performance of the image forming substance onto the recording medium, improve the image quality while utilizing the characteristics of the base material, and improve the reusability of the recording medium and the intermediate recording medium.

Further, for example, as described in claim 5, in the coating layer, an inorganic salt or an organic conductive agent may be added to the material.

That is, the recording medium must have a predetermined surface roughness and surface resistance in order to improve the transportability.
When is used, it is effective to add an electrolyte to lower the conductivity and lower the surface resistance in order to improve the transportability. This electrolyte can be, for example, chlorides such as sodium, potassium, calcium and magnesium, sodium sulfate and sodium aluminate as inorganic salts, and organic conductive agents such as quaternary ammonium salts and polystyrene. Sulfonic acid, sodium formate, glycerin, uric acid, and the like can be used. Particularly, when the present applicant has conducted tests, the organic conductive agent was found to be tetrafluoroborate / tetra-n-butylammonium (Tetra-n- butylammonium Tetrafluor
oborate, molecular weight: 329.27) was particularly good.

According to the above configuration, since the coat layer is formed of a material to which an inorganic salt or an organic conductive agent is added,
By lowering the surface resistance of the recording medium and the intermediate recording medium, eliminating sticking due to static electricity between the recording medium and the intermediate recording medium at the time of conveyance of the recording medium and the intermediate recording medium in the image forming apparatus and the image forming substance removing apparatus, It is possible to prevent conveyance troubles such as double feeding of the recording medium and the intermediate recording medium, improve the conveyance performance, and ensure the reusability of the recording medium and the intermediate recording medium while securing good image quality. Can be improved.

Further, for example, in the recording medium or the intermediate recording medium, the surface roughness on which the coating layer is formed is 5 to 10 in maximum surface roughness.
It may be in the range of μm.

According to the above configuration, the surface roughness on which the coating layer is formed is set to a maximum surface roughness in the range of 5 to 10 μm. It is possible to prevent the recording medium and the intermediate recording medium from sticking to each other in the substance removing device, prevent transport troubles such as double feeding of the recording medium and the intermediate recording medium, and improve the transport performance, The reusability of the recording medium and the intermediate recording medium can be improved while ensuring image quality.

Further, for example, as described in claim 7, the base material may be a paper mainly composed of cellulose.

According to the above configuration, since the base material is a paper mainly composed of cellulose, the feel of the recording medium or the intermediate recording medium can be used without any discomfort as the same feel as that of ordinary paper which is usually used. It is possible to improve the reusability of the recording medium and the intermediate recording medium while securing good image quality.

Further, for example, the base material may be a plastic material.

According to the above configuration, since the base material is made of a plastic material, the rigidity of the recording medium and the intermediate recording medium can be improved, and the occurrence of peeling wrinkles and transfer wrinkles can be prevented. It is possible to improve the reusability of the recording medium and the intermediate recording medium while ensuring good image quality.

Since the recording medium and the peeling member are pressurized with a pressure lower than the pressure, the image forming substance can be efficiently transferred and removed from the recording medium to the peeling member while reducing power consumption, and the recording medium can be efficiently reproduced. can do.

In this case, for example, as set forth in claim 10, the heating means is formed in a drum shape which is provided with a heating member for heating the recording medium to the heating temperature and is driven to rotate, and wherein the peeling member is provided. Is disposed so as to cover a predetermined area of the drum-shaped heating unit, and rotates with the rotation of the heating unit. The recording medium is in a state where the surface on which the image is formed faces the peeling member. The pressing unit may be held between the drum-shaped heating unit and the peeling member, and the pressurizing unit may press the peeling member against the heating unit with the pressure.

According to the above construction, the heating member for heating the recording medium to the heating temperature is incorporated therein, and the peeling member is provided so as to cover a predetermined area of the heating means formed in a drum shape which is driven to rotate. Since the medium is sandwiched between the drum-shaped heating means and the peeling member in a state where the surface on which the image is formed faces the peeling member, and the peeling member is pressed against the heating means by the pressing means, the size is small. With a simple configuration, the image forming substance can be efficiently transferred and removed from the recording medium to the peeling member while reducing power consumption, and the recording medium can be efficiently and inexpensively reproduced.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. It should be noted that the embodiments described below are preferred embodiments of the present invention, and therefore, various technically preferable limitations are added. However, the scope of the present invention is not limited to the following description. The embodiments are not limited to these embodiments unless otherwise specified.

FIGS. 1 and 2 show a recording medium, an image forming substance removing apparatus and an image forming substance removing apparatus to which the first embodiment of the recording medium, the image forming substance removing apparatus and the image forming substance removing method of the present invention is applied. It is a figure showing a method.

FIG. 1 is a schematic structural view of an image forming substance removing apparatus 1 to which a first embodiment of a recording medium, an image forming substance removing apparatus and an image forming substance removing method according to the present invention is applied. The removing device 1 includes a sheet feeding unit U1, a removing unit U2, a cleaning unit U3, a sheet discharging unit U4, and the like.

The image forming substance removing apparatus 1 feeds a recording medium on which an image has been recorded one by one from a sheet feeding unit U1 to a removing unit U2, and heats and presses the recording medium with a peeling member in the removing unit U2. While transferring the image forming substance on the recording medium to the peeling member, and removing the image forming substance from the recording medium.
The image forming substance transferred to the peeling member is removed by the cleaning unit U3, and the peeling member is reused for reproducing the recording medium.

Hereinafter, the units U1 to U4 will be sequentially described. The paper supply unit U1 includes a paper supply case 101, a paper supply roller 102, a pair of registration rollers 103, a conveyance roller 104, and the like. In the paper supply case 101, a plurality of recording media 2 to be reproduced are stored. Is done.

In the paper feed case 101, although not shown,
A bottom plate on which the recording medium 2 is placed;
It is urged upward by a spring (not shown) or the like to lift the end of the recording medium 2 in the paper feed case 101 on the paper feed roller 102 side upward.

The paper feed roller 102 is rotated at a predetermined timing by a drive motor (not shown) or the like, and sequentially feeds the recording media 2 in the paper feed case 101 from the uppermost recording media 2.

The recording medium 2 sent out by the paper feed roller 102 is separated from the multi-fed paper by a separation mechanism (not shown), and only one recording medium 2 is moved by a registration roller 103 for timing adjustment and skew correction. Transport roller 104
Is transported to the registration roller 1
03 to remove the recording medium 2 sent out from the unit U
Convey to 2.

As shown in FIG. 2, the recording medium 2 includes a base material 3
The coating layers 4a and 4b are formed on both the front and back surfaces of the.

The substrate 3 can be made of paper, plastic film, or the like.
Excellent in durability. In this case, the recording medium 2
In order to improve the transportability of the recording medium 2 when forming an image with an image forming apparatus such as a copying machine or a printer, the recording medium 2 needs to have a predetermined surface roughness and surface resistance. The surface roughness is required to be about 5 to 10 μm in order to prevent conveyance troubles such as double feeding of the recording medium 2. However, paper has a proper surface roughness of the above level (9 to 10 μm).
(About 10 μm), and is suitable as the base material 3. However, when the plastic film is used as the base material 3 because the surface flatness is too good,
It is necessary to provide an appropriate surface roughness. As a method of imparting surface roughness to the surface of this plastic film,
For example, there is a method of rolling the roughness on the plastic film surface using a roller having a certain roughness, or roughening the plastic film surface to a predetermined roughness by sand blasting or the like. After forming 4b, a method of roughening the surfaces of the coat layers 4a and 4b with sand blast or the like, or as a filler in a coating solution,
A method in which fine powder solids are contained and simultaneously applied may be adopted.

The coat layers 4a and 4b are used to improve the reusability of the recording medium 2 and improve the image quality.
It is required that the releasability from the image forming substance formed on the recording medium 2 be good and the compatibility with the image forming substance be good.

As the coating layers 4a and 4b, first, from the viewpoint of releasability, a resin containing fluorine is preferable as a material (coating material). As the resin containing fluorine, for example, PFA (tetrafluoroethylene / porfluoroalkyl vinyl ether copolymer, critical surface tension 17.8 mN / m) used as a surface release agent for the fixing roller of an electrophotographic image forming apparatus, and intermediate transfer of an image forming apparatus ETF used as a belt
E (ethylene / tetrafluoroethylene copolymer, critical surface tension 22.0 mN / m). These materials have material properties such that toner as an image forming substance does not adhere or toner adheres but does not adhere, and is suitable as the coat layers 4a and 4b. Further, silicon-based oil or the like used for releasing the surface of the fixing roller of the image forming apparatus is also a material having good releasability, and is suitable as the coating layers 4a and 4b. Further, as the coating layers 4a and 4b, in addition to such fluorine-containing resin and silicone-based oil, a certain surfactant or a substance having a numerical value that is different in surface energy from an image forming substance, or the like is used. Can be used. That is, the critical surface tension of a general toner as an image forming substance is 32 to 3
Since it is 3 mN / m, the further away from this value, the lower the fixability, and conversely, the releasability improves.

However, as described above, the recording medium 2 is used to improve the image quality.
It is also required that the image formed thereon has good fixability and storage stability. That is, the recording medium 2 on which the image is recorded
When the image forming substance on the recording medium 2 is transferred to another recording medium 2 on which the image forming substance is superimposed,
If the image blurs or falls off when touched by hand,
This is because the image quality is degraded and cannot play a role as the recording medium 2.

The fixing property of the image forming substance is determined by the image forming substance and the surface of the recording medium 2, that is, the coating layer 4.
a and 4b can be ensured by having mutual compatibility that enables the transition to the bonded state. Having the compatibility means that the plasticizer is homogeneously mixed with the polymer substance without causing phase separation.
When the materials a and b have such characteristics with respect to the image forming substance, the fixing property of the image forming substance can be ensured.

However, when the image forming material and the coating layers 4a and 4b are actually compatible with each other at the time of image formation and reproduction, the image forming material on the recording medium 2 is removed by the image forming material removing device 1. Therefore, in the image forming substance removing apparatus 1, as described later, in the removing unit U <b> 2, the temperature is equal to or higher than the softening point of the image forming substance and the coating layer 4 a is used. The recording medium 2 is heated to a temperature lower than the thermal deformation temperature of the material of the coating layers 4a and 4b, and the recording medium 2 and a peeling member described later are pressed at a pressure lower than the thermal deformation pressure of the material of the coating layers 4a and 4b. .

Examples of the material of the coating layers 4a and 4b having the characteristics of the release property and the compatibility include, for example,
PVDF (polyvinylidene fluoride, critical surface tension 25
mn / m) or a copolymer of PVDF and another polymer.

Since this PVDF is a family of fluororesins, it is basically an inactive resin, has a generally-releasable releasability, and has an overlay that does not easily adhere to dust and dirt. (For example, Kureha KFC film manufactured by Kureha Chemical Industry: trade name). Therefore, PVDF has poor adhesiveness and has a property of easily peeling or transferring the image forming substance. On the other hand, PVDF is known to have compatibility with acrylic resins and vinyl acetate resins (“Fluorine Resin Handbook”, Nikkan Kogyo Shimbun, 1991.11.
30, issued on page 394). Also, as a plasticizer for PVDF, saturated polyester is known, and it is known that the plasticizing effect is large and the compatibility is good. Kogyosha, issued December 1, 1979, see p. 152).

Generally, examples of the binder resin of the image forming substance used in the image forming apparatus include the following. As a binder resin for heat fixing, polystyrene, styrene-acrylic resin,
There are polyester-based resins, epoxy resins, vinyl butyral resins, polyamide resins, polyolefins, and the like.Moreover, for pressure fixing, polyethylene, ethylene-vinyl acetate resin, styrene-butadiene rubber, and other waxy rubber-like resins may be mentioned. it can. Above all, styrene-acrylic (esterified state of acrylic acid) resin is particularly frequently used, and subsequently, polyester-based resin is often used. However, a styrene-acrylic resin may be contained in the polyester resin binder in some cases (see JP-A-5-27478 and JP-A-9-43899).

Among the image forming materials, those formed of the above-mentioned styrene-acrylic resin and those formed of a polyester-based binder resin containing the styrene-acrylic resin show compatibility with PVDF, P
VDF applies a recording medium 2 to these image forming substances.
Has sufficient fixability as the coating layers 4a and 4b.

Further, a polyester toner composed of only a polyester resin binder containing no styrene-acrylic resin has an affinity for PVDF, and is sufficient for the recording medium 2 when an image is formed by an image forming apparatus. Has fixing ability. That is, PVDF is a highly polar resin among fluororesins, and has the same ester bond as a compatible acrylic resin, vinyl acetate, and a saturated polyester which is a plasticizer of PVDF. It has an affinity for the polyester toner which is a substance, and PVDF is suitable for these image forming substances as the coating layers 4a and 4b of the recording medium 2.

Further, the coating layers 4a and 4b are formed by applying the above-mentioned coating material on the surface of the substrate 3 or the like, and the amount thereof is 50 g based on the linear expansion coefficient or the coefficient of thermal expansion with the substrate 3. / M ² or less is appropriate. That is, when the amount of the coating layers 4a and 4b is within the above range, even after the recording material 2 is repeatedly reused, the coating layers 4a and 4b and the There is no significant loss of texture. According to the results of experiments conducted by the present applicant, the lower limit of the amount of the coating material of the coating layers 4a and 4b indicates that when the base material 3 is paper, the coating amount is about 2 g / m ² , Cannot be covered, and the image forming substance may be left behind. Therefore, the above lower limit is about 5 g / m ² . That is, when the base material is paper, if the coating layer material has a coating amount of about 2 g / m ² , the residual image density after image removal is as high as 0.50 as an OD value (measured optical reflection density value). However, it has been observed that an image such as an original character is recognized. However, when the coating layer material is applied in an amount of about 5 g / m ² or more, the OD value is reduced by one digit from 0.02 to 0.04. As a result, the original image was not recognized, and good image removal quality could be secured. When the substrate 3 was a plastic film, even when the amount of the coating material was about 2 g / m ² , the image forming substance was completely transferred without being left behind.

As described above, the recording medium 2 needs to have a predetermined surface roughness and a predetermined surface resistance in order to improve the transportability, but the coating material of the coating layers 4a and 4b is required. In the case where PVDF is used, it is preferable to mix an electrolyte with respect to the surface resistance in order to lower the conductivity. This electrolyte can be, for example, chlorides such as sodium, potassium, calcium and magnesium, sodium sulfate and sodium aluminate as inorganic salts, and organic conductive agents such as quaternary ammonium salts and polystyrene. Sulfonic acid, sodium formate, glycerin, uric acid, and the like can be used. Particularly, when the present applicant has conducted tests, the organic conductive agent is tetrafluoroborate / tetra-n-butylammonium (molecular weight: 329. 27) was particularly good.

Then, an image is formed on the recording medium 2 by an electrophotographic method using dry toner.
