[0004]

Problems to be Solved by the Invention Japanese Patent Application No. Hei 9-116 mentioned above.
In the apparatus for reproducing an image holding member of No. 129, the amount of liquid, more specifically, the amount of liquid required, is more than necessary in consideration of spontaneous evaporation and flow of the applied liquid and forced evaporation due to heating by pressurizing and heating means. Of liquid that cannot be absorbed by the swelling layer. However, when the pressurizing and heating by the pressurizing and heating means are performed in a state where the image holding member is sandwiched between a heating member having a built-in heating element and a surface-endless movable heating member and a peeling member, Such troubles occur.

FIG. 8 is an explanatory diagram for explaining the occurrence of this problem. FIG. 8A is a diagram for explaining a state in which the sheet-shaped image carrier 1 passes through a pressure heating unit having the heating drum 21 as the heating member and the peeling member 28, and FIG. FIGS. 8A and 8B are views for explaining a state in which the subsequent image holding member enters the above-described pressurizing and heating means.
(C) is an explanatory view of the succeeding image carrier discharged from the pressurizing and heating unit. First, in FIG. 8A, the image carrier 1 to which the liquid is applied by the liquid application unit (not shown) is placed at the entrance (hereinafter, referred to as an exfoliation) of the opposing portion between the exfoliation member 28 of the pressurizing and heating unit and the heating drum 21. (Referred to as an entrance), the excess liquid on the image carrier 1 is filtered, and a liquid pool 101 is formed at the separation entrance. It should be noted that reference symbol A in FIG.
Indicates the rear end of the image carrier 1.

At the time of continuous paper feeding, as shown in FIG. 8 (b), at a predetermined distance from the rear end A of the image holding member 1, the succeeding image holding member 1 'is connected to the pressing and heating means. enter in.
The subsequent image carrier 1 'is sandwiched between the heating drum 21 of the pressurizing and heating means and the peeling member 28 after passing through the liquid reservoir. At this time, when the liquid applying means of the reproducing apparatus is configured to apply the liquid only to one surface of the image holding member and not to apply the liquid to the other surface, When the subsequent image carrier 1 'passes through the reservoir, the liquid adheres to the surface of the image carrier 1' to which the liquid is not applied. The liquid adhesion is different from the liquid application by the liquid applying means, and is not always uniformly attached to the image holding member. Therefore, FIG.
As shown in (c), the surface of the image holding member 1 ′ to which the liquid is not applied is a bubble mark or a liquid evaporation mark due to the boiling effect of the liquid caused by the heat of the heating drum 21. However, there is a problem that the trace of the liquid 102 is generated in a patchy manner.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to generate traces of liquid bubbles and traces of liquid evaporation on the surface of an image carrier to which liquid is not applied. It is an object of the present invention to provide a reproducing apparatus for an image carrier which can prevent the occurrence of the image.

[0008]

In order to achieve the above object, the present invention is directed to an image forming apparatus comprising: a non-liquid absorbing base provided with a liquid absorbing swelling layer; A liquid applying means for applying an amount of liquid that cannot be absorbed by the swelling layer, and an image forming surface of the image carrier to which the liquid is applied, and a release member made of a material through which the vapor of the liquid does not pass. In the combined state, a pressurizing and heating means for heating the image carrier and pressing the image carrier and the peeling member is separated from the image carrier and the peeling member which are in contact with each other by the above-mentioned pressure. An image forming member for removing an image forming substance constituting an image formed on the image holding member, and reproducing the image holding member as an image forming member capable of forming an image. ,
The pressurizing and heating by the pressurizing and heating means are performed in a state in which the surface is endlessly moved, the heating member with a built-in heating element, and the image holding member sandwiched between the peeling member, and
At least a part of the surface of the heating member is formed of a liquid absorbing member.

In this image carrier reproducing apparatus, the pressurizing and heating by the pressurizing and heating means is performed by sandwiching the image carrier between a heating member having a built-in heating element whose surface moves endlessly and the peeling member. It is performed in the state where it is made. Then, in such a state, when the image holding body to which the amount of liquid that cannot be absorbed by the swelling layer is applied is pressurized and heated, the excess liquid of the image holding body is filtered, and the pressurized heating is performed. A liquid pool is formed at the entrance of the opposing portion between the heating member and the peeling member of the means. Thereafter, a portion formed by the liquid absorbing member on the surface of the heating member comes into contact with the liquid pool by endless movement of the surface, and the liquid pool is eliminated by absorbing a part of the liquid.

According to a second aspect of the present invention, in the image carrier reproducing apparatus of the first aspect, the surface of the liquid absorbing member of the heating member is moved between the surface and the separating member when the surface faces the separating member. The gaps are formed between them.

In the image carrier reproducing apparatus, when the surface faces the peeling member, a gap is formed between the surface of the liquid absorbing member of the heating member and the peeling member. It is easier to attract and hold in space.

According to a third aspect of the present invention, in the image carrier reproducing apparatus of the first aspect, the liquid absorbing member is a member having elastic characteristics.

In the image carrier reproducing apparatus, since the liquid absorbing member is a member having elastic characteristics, the peeling member and the heating member come into close contact with each other by the pressurization by the pressurizing and heating means.

[0014] The invention of claim 4 is the invention of claim 1, 2, or
In the reproducing apparatus for an image carrier according to the third aspect, the liquid absorbing member is detachably provided on the heating member.

In the reproducing apparatus for an image holding member, the liquid absorbing member is detachable from the heating member, so that the absorbing performance of the liquid absorbing member is reduced, and that the dirt such as dust and image forming substance adheres. If it does, it can be removed and replaced with a new one, or cleaned.

According to a fifth aspect of the present invention, in the image carrier reproducing apparatus of the first, second, third, or fourth aspect, a portion of the surface of the heating member other than a region facing the peeling member is provided.
A pressurizing member for performing pressurization is provided.

In the image carrier reproducing apparatus, the pressing member applies pressure to a portion of the surface of the heating member other than a region facing the peeling member. Thus, the liquid absorbing member on the surface of the heating member can be pressurized in a region other than the opposed region, and the liquid absorbed by the liquid absorbing member can be squeezed out. Further, dirt attached to the liquid absorbing member can be removed together with the liquid.

According to a sixth aspect of the present invention, in the apparatus for reproducing an image carrier according to the first, second, third, fourth, or fifth aspect, the peripheral length of the heating member is set to an image. The length of the holder in the transport direction is set to a natural number times the length obtained by adding the distance between the image holders to be transported.

In this image carrier reproducing apparatus, the peripheral length of the heating member is a natural number of the length of the image carrier in the transport direction plus the distance between the transported image carriers. Since it is twice, the image carrier always contacts the same position on the surface of the heating member. This makes it possible to dispose the liquid absorbing member at the above-mentioned interval where the liquid absorbing member is not in contact with the image holding member, and to prevent the liquid absorbing member from contacting the image holding member.

According to a seventh aspect of the present invention, in the apparatus for reproducing an image carrier according to the sixth aspect, there is provided a detection unit provided at a predetermined position on the surface of the heating member, and detection means for detecting the detection unit. And a control unit for feeding or transporting the image carrier in synchronization with the movement of the surface of the heating member based on a detection signal from the detection unit.

In the reproducing apparatus for an image carrier, the detecting means detects a portion to be detected set at a predetermined position on the surface of the heating member, and based on the detection signal, detects the movement of the surface of the heating member. The image carrier is fed or transported in synchronization. Thus, the image carrier can be automatically fed or conveyed so that the image carrier does not contact the liquid absorbing member.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the image carrier reproducing apparatus according to the present invention will be described below. The reproduction device of the image holding member of the present embodiment is a normal electrophotographic method, a thermal transfer method, a thermoplastic or hot-melt image forming substance such as an ink jet method or a printing method using hot melt ink is used, Also, the present invention relates to an image carrier reproducing apparatus for removing and reproducing an image forming material from an image carrier recorded by an image recording method in which the image forming material is formed in the form of a film near the surface of the image carrier.

Here, the above-mentioned film form does not necessarily mean that the entire image forms a single film, but merely that the image forming substance does not penetrate deeply into the image carrier or contains a dye. This means that the image forming substance is not almost adsorbed on the image carrier at a molecular level as in the case of printing with the aqueous ink. Therefore, for example, an image formed by an electrophotographic method using a dry toner
If the image is interrupted in one character image or if the toner particles do not penetrate deep into the image carrier, even if one toner particle exists independently, It can be regarded as a film-like image from the principle, and is included in the category of the image that can be removed by the method of the present embodiment.

The image carrier used in the present embodiment absorbs a liquid on a non-liquid-absorbing substrate which does not absorb a liquid as disclosed in JP-A-6-222604 and JP-A-7-31523. An image holding member provided with a swellable liquid absorbing layer.

Examples of the material of the non-liquid-absorbing substrate include polyesters such as polyethylene terephthalate and polyethylene naphthyl; plastics using cellulose as a raw material such as cellulose triacetate, cellulose diacetate and nitrocellulose; bisphenol A; Films made of plastics such as polycarbonate, polyimide, 6,6-nylon, 6-nylon, aramid, and the like, and polyethersulfone, polyetheretherketone, polyphenylenesulfite, polypropylene, and the like can be used. . In the case of an image carrier requiring transparency, such as an OHP sheet, these materials can be used in a relatively pure state, but it is required that the material be opaque as an image carrier in place of paper. If it is, titanium oxide, zinc oxide, clay, calcium carbonate, adding white pigments such as barium sulfate to the above materials,
A foamed product can also be used. Further, a paper impregnated with a resin such as an emulsion of an acrylic polymer and dried can also be used.

As the liquid-absorbing swelling layer, a polymer crosslinked so as not to be dissolved by a liquid (hereinafter referred to as "image removal accelerating liquid") to be applied to the image carrier can be used. In particular, it is preferable to use a liquid mainly composed of water as the image removal accelerating liquid from the viewpoint of safety. Therefore, it is preferable to use a hydrophilic polymer. Specific examples include polymers having a carboxylic acid group, a phosphoric acid group, a sulfonic acid group, a hydroxyl group, an amide group, an amino group, and a polymer having a polyethylene glycol chain. More specifically, acrylic acid and its salts, methacrylic acid and its salts, vinyl alcohol, hydroxymethyl methacrylate, hydroxypropyl methacrylate, acrylamide, N-
Polymers or copolymers such as isopropylacrylamide, N, N-dimethylaminoethyl acrylate, N, N-dimethylaminoethyl methacrylate, N, N-dimethylaminopropyl acrylamide, and vinylpyrrolidone, and polyethylene glycol can be exemplified.

As the crosslinking agent, a crosslinking agent having a plurality of unsaturated bonds, such as N, N-methylbisacrylamide, an isocyanate crosslinking agent, an epoxy crosslinking agent, and formalin are used. As a method for crosslinking, in addition to using a crosslinking agent, electron beam irradiation, irradiation with electromagnetic waves such as ultraviolet rays and X-rays, and heating can also be used.

In the case of an image carrier which requires transparency in the swelling layer such as an OHP sheet, it is preferable that the swelling layer be substantially uniform, but it is opaque as an image carrier in place of paper. When it is required, a layer in which particles of the above-mentioned polymer or starch are dispersed in a binder may be used.

The swelling layer may be provided on only one side of the above-mentioned substrate. However, providing the swelling layer on both sides can prevent curling, can be used without discrimination between front and back sides during image formation, and can be repeatedly used many times. Is preferred.

The swelling layer is preferably provided so that the thickness on one side is 5 μm or less. If it exceeds 5 μm, the amount of the image removal accelerating liquid used increases, and the drying means for drying the image removal accelerating liquid after removing the image forming substance becomes large-scale. In addition, since the swelling layer is apt to crack, this is a serious problem particularly when transparency is required as in an OHP sheet.

The swelling ratio of the swelling layer is 1.5 to 20.
It is preferable to select a degree of crosslinking and an image removal accelerating liquid so as to double the degree. When it exceeds 20 times, there arises a problem that the use amount of the image removal accelerating liquid increases as in the case where the swelling layer is too thick. When the swelling ratio is high, the strength of the swelling layer decreases, and the number of repetitions that can be used decreases.

After the image-forming substance is removed from the image carrier, the image carrier must be dried in order to make it reusable. If the amount of the image removal accelerating liquid applied to the image holding member is large, the amount of energy required for drying increases, so the amount of the image removal accelerating liquid applied is preferably 2 ml or less per A4 size. Therefore, the saturated absorption amount calculated from the product of the thickness of the swelling layer and the swelling ratio is 2 m per A4 size.
It is particularly preferable to set the thickness and the swelling ratio of the swelling layer within a range not exceeding 1.

FIG. 1 is a schematic configuration diagram of a reproducing apparatus according to the present embodiment. In FIG. 1, a sheet-shaped image carrier 1 on which an image is formed by electrophotography or the like and which becomes unnecessary
Is manually introduced into the paper feed roller 3 along the guide plate 2 as a manual placing member. The paper feed roller 3 is driven and rotated by a drive unit (not shown) when the image holder is detected by the image holder sensor (not shown) to be introduced into the apparatus. The image carrier is operated to be conveyed to a liquid supply unit as a liquid application unit.

The liquid supply section includes a liquid container 13, a liquid application roller 12, a squeeze roller 15, a pressing roller 14, and the like for holding the image removal accelerating liquid 11 therein.
The liquid application roller 12 can be constituted by, for example, a so-called gravure roller having a large number of holes on its surface. In the case of the gravure roller, the amount of liquid held on the surface can be changed by changing the size and depth of the hole. A part of the liquid application roller 12 is shown in FIG.
As shown in FIG. 2, the image carrier 1 is arranged so as to be immersed in the image removal accelerating liquid 11, and is rotated by a drive system (not shown) in the same direction as the conveyance of the image carrier 1 so as to be equal to the linear speed of the paper feed roller 3.
Excessive image removal accelerating liquid 11 adhering to liquid applying roller 12
Is the squeeze roller 1 that rotates with the liquid application roller 12.
5 removes from the liquid application roller 12. The liquid application roller 12 applies the image removal accelerating liquid 11 to the image carrier 1 by contacting the image carrier 1. The pressing roller 14 is configured to press only the end of the image holding member toward the liquid applying roller 12 with a disk having a protrusion on the outer periphery thereof, such as a spur. When a roller having a smooth surface is used, the image removal accelerating liquid 11 tends to adhere to the back surface (the surface on which no image is formed) of the image carrier, which is not preferable.

In this embodiment, in order to efficiently and surely remove the image forming substance from the image carrier, the image carrier is applied within the time of the step of applying the image removal accelerating liquid to the image carrier. An amount of the image removal accelerating liquid that cannot be absorbed by the swelling layer is applied to the image carrier.

The above-mentioned image removal accelerating liquid is a liquid for swelling the swelling layer of the image carrier, but from the viewpoint of safety, water or a liquid mainly composed of water is preferable. As the image removal accelerating liquid, those containing a surfactant and a water-soluble organic compound in addition to water can be used. By using the surfactant, it is possible to uniformly wet the image carrier, the image on the image carrier, and a member such as a roller for supplying the image removal promoting liquid with the image removal promoting liquid. The water-soluble organic compound acts as a wetting agent or a solubilizing agent for the surfactant.

Examples of the surfactant that can be used in the image removal accelerating liquid include a nonionic surfactant, an anionic surfactant, a cationic surfactant, and an amphoteric surfactant.

Examples of the nonionic surfactant include polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene alkyl esters, polyoxyethylene alkyl sorbitan esters, polyoxyethylene alkyl amines, and glycerin. Fatty acid esters, decaglycerin fatty acid esters, polyglycerin fatty acid esters, sorbitan fatty acid esters, propylene glycol fatty acid esters, polyethylene glycol fatty acid esters, polyoxyethylene polyoxypropylene alkyl ethers, polyoxyethylene polyoxypropylene block Polymers, perfluoroalkyl phosphoric acid esters, polyoxyethylene-modified polydimethylsiloxanes, and the like. Kill.

The above-mentioned anionic surfactants include higher fatty acid salts, N-acyl amino acid salts, polyoxyethylene alkyl ether carboxylate, acylated peptides, alkyl sulfonates, alkyl benzene sulfonates, alkyl naphthalenes. Sulfonate, mono- or dialkyl sulfosuccinate, α-olefin sulfonate, N-acyl sulfonate, alkyl sulfate, polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl aryl ether sulfate, alkylamide sulfate Salt, monoalkyl phosphate, dialkyl phosphate, trialkyl phosphate, monopolyoxyethylene alkyl ether phosphate, bispolyoxyethylene alkyl ether phosphate, trispolyoxyethylene alkyl ether phosphate, polyoxy Tylenealkylaryl ether phosphate, perfluoroalkylcarboxylate, perfluoroalkylsulfonate, perfluoroalkenylarylsulfonate, N-perfluorooctanesulfonylglutamate, perfluoroalkyl-N-ethylsulfonylglycine, 3 -(Ω-fluoroalkanoyl-N-ethylamino) -1-propanesulfonic acid salt, perfluoroalkylethylphosphate, carboxylic acid-modified polydimethylsiloxane, sulfonic acid-modified polydimethylsiloxane, and the like.

Examples of the cationic surfactant include higher alkylamine salts, higher alkyl quaternary ammonium salts, alkylbenzeneamine salts, alkylbenzene quaternary ammonium salts, and alkyl heterocyclic quaternary ammonium salts. Examples of the amphoteric surfactant include betaine and aminocarboxylic acid.

In order to improve the wettability of the image removal accelerating liquid to an image carrier or an image forming substance, it is not always necessary to use a surfactant. For example, alcohols such as methanol and ethanol, The same effect can be obtained by adding a water-soluble organic compound such as acetone, carbitol, and sorbitol. However, in order to improve wettability by adding only these organic compounds to water, it is necessary to add at least 5% by weight or more of the whole liquid. By using a surfactant,
Since the wettability can be improved by using a small amount, even when an excess liquid adheres, the trace of the adhesion of the liquid hardly remains. In the removal, it is easy to maintain the transparency of the image carrier after reproduction. When a solvent having a relatively low boiling point, such as methanol or ethanol, is used, there is no problem of the above-mentioned trace of the liquid, but it is not preferable in that vapor of the solvent is generated.

Therefore, it is preferable to add a surfactant to the image removal accelerating liquid in the present embodiment.
For use in HP sheet regeneration, it is preferable to minimize the addition of surfactants. The amount of the surfactant to be added is preferably 0.05 to 2.0% by weight of the entire image removal accelerating liquid. Since wettability cannot be obtained, it is difficult to remove the image. On the other hand, when the content exceeds 2.0% by weight, a liquid trace is likely to be formed on the image carrier after reproduction.

Preferred examples of the water-soluble organic compound to be added to the above-mentioned image removal accelerating liquid include ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, glycerin, 1,5- Pentanediol, 1,6-hexanediol, 2-methyl-2,4-pentanediol, and the like. It is preferable that the amount of these water-soluble organic compounds added to the image removal accelerating liquid is not more than 2.0% by weight for the same reason as the surfactant.

In a state where the image forming surface of the image carrier 1 to which the image removal accelerating liquid 11 is applied and the peeling member 28 are overlaid, heating of the image carrier 1 and application of the image carrier 1 and the peeling member 28 are performed. The peeling section as a heating and pressurizing means for applying pressure is provided with a heating drum 21 as a metal heating member having a built-in heater 22 as a heating element such as a halogen lamp, and a surface coated with an elastic member such as silicone rubber. Metal pressure roller 27, entrance roller 23, separation roller 24 as image carrier separation means, tension roller 25, cleaning backup roller 26, rollers 23, 24, 2
An endless belt-like member provided so as to inscribe the inside 5 and 26 is composed of a heating drum 21 as the heating member and a peeling member 28 for holding the image carrier 1 therebetween.

The heating drum 21 is formed of a metal such as aluminum having excellent heat conductivity, and its surface is generally bare metal or is coated with Teflon so as not to be easily stained. It is. The heating drum 21 is driven to rotate in the direction of the arrow by driving means (not shown). Pressure is applied between the pressure roller 27 and the heating drum 21 by a biasing means such as a spring or a hydraulic pressure (not shown), and a nip is formed between the roller and the drum. The tension roller 25 is configured to apply tension to the endless belt-shaped peeling member 28 by a biasing means such as a spring or a hydraulic pressure (not shown). The temperature of the heating drum 21 is controlled by a temperature element (thermistor) not shown.

The peeling member 28 is a member for transferring and peeling the image forming substance from the image carrier.
Although a material having high adhesiveness to the image forming substance is selected, in the present embodiment, in order to prevent evaporation of the components of the image removal promoting liquid, It is also required to have the property of not allowing the vapor to pass through.

Specific examples of the material of the peeling member include:
Isoprene rubber, neoprene rubber, chloroprene rubber,
Synthetic rubbers such as silicone rubber, butadiene rubber, and fluorine rubber, natural rubbers, epoxy resins such as bisphenol / echlorochlorohydrin condensates, alkyd resins, urea formaldehyde resins, butyl urea formaldehyde resins,
Amino resins such as butylated melamine formaldehyde resin and benzoguanamine formaldehyde resin, phenolic thermosetting resins such as terpene phenol resin, phenol ether resin and phenol resin, polyvinyl chloride,
Polyvinylidene chloride, vinylidene chloride-acrylonitrile copolymer, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer, ethylene-tetrafluoroethylene copolymer, polyvinylidene fluoride, vinyl copolymer polyvinyl butyral, polyvinyl Vinyl polymers such as formal, polypropylene and polyethylene; acrylic resins such as polybutyl acrylate, polymethacrylic acid and polymethyl methacrylate; polyimides;
Polyamides such as nylon, 6-nylon, polycarbonate, polyethersulfone, polyetheretherketone, polyethylene terephthalate, polyethylene naphthalate, polyesters such as aromatic polyester, polyphenylene sulfide, polyparabaranic acid,
Thermoplastic or thermosetting synthetic resins such as polyether nitrile and aramid; metals such as nickel, stainless steel and aluminum; oxides thereof; and ceramic materials.

These materials can be used alone, but they can also be used in combination by laminating, alloying, or adding other additives such as glass fiber, whisker, carbon, silica, titanium oxide, and the like. The optimal material for the peeling member should be selected according to the type of the image forming material to be peeled and the image forming material removal process, but repeated use of the peeling member is advantageous in various points such as lowering the reproduction cost. In this case, relatively high heat resistance and surface stability are required. Examples of the material of the peeling member preferable from the removal properties and durability of the image forming substance include polyethylene terephthalate, polyethylene naphthalate, polyetheretherketone, polyphenylenesulfide, polyparabaranic acid, polyethernitrile, aramid, polyimide, polyetherimide,
Examples include stainless steel, nickel, and alumite.

The image holding member 1 having the image forming surface provided with the image removing accelerating liquid 11 by the liquid supply unit is inserted between the heating drum 21 and the peeling member 28 in the vicinity of the entrance roller 23, and The first image holding surface and the peeling member 28 are overlapped. The image carrier 1 having the surplus image removal promoting liquid 11 on its surface is heated by the heating drum 21 in a path from the entrance roller 23 to the separation roller 24. In this heating, the image removal accelerating liquid 11 is absorbed up to the swelling layer located below the image forming substance formed in the form of a film, and the adhesive strength between the image forming substance and the image carrier 1 is reduced.

Further, in the peeling section, the image forming substance of the image formed on the image carrier 1 is heated by the heating drum 21 and reaches a temperature above the softening point before reaching the pressure roller 27. On / off of the heater 22 of the heating drum 21 is controlled. The heating temperature is selected at an appropriate level depending on the temperature characteristics of the viscoelasticity of the imaging substance to be used. When a general dry toner for electrophotography is used, the temperature is preferably from 60 to 130 ° C, particularly from 70 to 110 ° C.
C is preferably set so that the image carrier 1 is heated. At a temperature lower than the preferred temperature range, the fluidity of the image-forming substance is insufficient, so that the image-forming substance does not sufficiently adhere to the peeling member, and transfer and peeling of the image-forming substance hardly occur. At a temperature higher than the preferred temperature range, the fluidity of the image forming substance becomes too high, and the image carrier 1 and the peeling member 2
At the time of separation from the image forming material 8, cohesive failure occurs inside the image forming material, so that it is difficult to completely remove the image forming material from the image carrier 1. When an appropriate fluidity is generated in the image forming substance by the heating in the above-mentioned temperature range, the image forming substance and the peeling member 28 are pressed by the pressure roller 27 so that the gap between the image forming substance and the peeling member 28 is formed. Adhesion can be created.

The effect of the heating path length in the peeling section is longer as the heating path length is longer.
It is difficult to completely prevent the evaporation of steam
It is preferable to set in the range of 10 to 1000 mm.
The heating path length is appropriately selected depending on the desired processing speed, the properties of the image forming substance to be removed, the state of adhesion of the image forming substance to the image carrier, and the like. When removing an image formed by a commonly used electrophotographic method at a linear velocity of 10 to 120 mm / sec, the heating path length is set to 20 to 2 mm.
It is particularly preferable to set it to 50 mm.

The peeling member 28 and the image carrier 1 are separated near the separation roller 24. The reason for the separation is that the peeling member 28 is conveyed along the separation roller 24, while the image carrier 1 tends to move in a linear direction due to its rigidity. If the adhesive force between the image carrier 1 and the image forming substance is not sufficiently reduced, it becomes difficult to separate the peeling member 28 from the image carrier 1. However, in the present embodiment, the swelling layer of the image carrier 1 By heating the image carrier 1 in a state where the excess image removal accelerating liquid 11 that cannot be absorbed is applied, the adhesive force between the image carrier 1 and the peeling member 28 is sufficiently reduced, so that separation is extremely easy. , And the possibility of causing a conveyance failure (jam) of the image carrier 1 is extremely reduced.

In the above-mentioned peeling section, the peeling member 28
Then, the image forming substance on the image carrier 1 is transferred, but the image forming substance on the peeling member 28 is removed by the cleaning member 31, and the peeling member 28 is used repeatedly. As the cleaning member 31, a roller having a blade formed in a spiral shape, a roller having a scourer-like surface in which a metal or organic polymer wire is wound in a loop, or a roller in which a metal or organic polymer wire is planted is preferably used. However, it is not always necessary to use a rotatable roller, and it is also possible to clean the peeling member 28 with a metal, ceramics, or organic polymer fixed blade.
The image forming substance 33 removed from the peeling member 28 by cleaning the peeling member 28 is accumulated in the container 32 and is disposed as appropriate.

The recording material 1 heated and pressed in the peeling section is separated from the peeling member 28 by separation claws 45a and 45b, conveyed along a paper discharge guide 41, and then discharged by discharge rollers 42 and 43. Conveyed on the guide plate 44,
It is discharged to the tray 46 and stocked.

As described above, the image forming substance is removed from the recording material 1 and reproduced in a reusable state.

In this embodiment, as shown in FIG. 2, a part of the surface of the heating drum 21 is formed by the liquid absorbing member 103. Specifically, a cut groove is provided in a predetermined arc range on the surface of the heating drum 21,
A liquid absorbing member 103 that easily absorbs and holds moisture or a liquid similar thereto is attached to the groove. As the liquid absorbing member, a fiber such as cloth, a nonwoven fabric, a water absorber used for diapers and the like can be used. In the illustrated example, the dimension of the liquid absorbing member in the width direction is set to be larger than the width of the conveyed image holding member. It should be noted that the white arrow in the drawing indicates the direction in which the image carrier is transported. In FIG. 2, the illustration of the pressure roller 27 is omitted.

As described above, when the image carrier 1 passes through the peeling section, a liquid pool is formed at the entrance of the peeling section. Thereafter, with the rotation of the heating drum 21,
When the liquid absorbing member reaches the liquid pool portion, the liquid in the liquid pool is absorbed by the liquid absorbing member 103. As a result, the liquid pool is eliminated, and the liquid does not adhere when the subsequent image carrier 1 enters the peeling section. Accordingly, it is possible to prevent the trace of bubbles and the trace of evaporation of the liquid from occurring on the surface of the image holding member reproduced by the adhesion of the liquid. Since the liquid absorbing member 103 is provided on the surface of the heating drum 21, the liquid absorbing member 103
The liquid absorbed in 03 is easily evaporated by the heat of the heating drum 103. Thereby, the liquid absorbing member 1
Liquid hardly accumulates in 03.

FIG. 3 is an explanatory view of the liquid absorbing member.
The portion formed by the liquid absorbing member 103 on the surface of the heating drum 21 is desirably configured such that a gap is formed between the portion and the peeling member 28 when the portion faces the peeling member 28. For example, as shown in FIG. 3A, the length r1 of the surface of the liquid absorbing member 103 from the center of the heating drum 21 is different from that of the heating drum 21 on the surface of the heating drum 21 other than the portion where the liquid absorbing member 103 is provided. 21 so as to be shorter than the length r0 from the center, that is, r
What is necessary is just to set so that 0> r1 may be established. With this configuration, the liquid absorbing member 103 spatially attracts and holds the liquid forming the liquid pool. Therefore, the liquid pool can be more favorably eliminated.

The liquid absorbing member 10 of the liquid absorbing member 103
3 and the surface of the heating drum 21 other than the portion where the liquid absorbing member 103 is provided, the length of the surface of the liquid absorbing member 103 from the center of the heating drum 21 and the liquid absorbing member 103 A step may occur not only when the length of the surface of the heating drum 21 other than the provided portion is different from the center of the heating drum 21 but also due to, for example, an error in the formation. In such a case, even if the peeling member 28 and the heating drum 21 are each driven at a constant speed, the curvature of the surface of the heating drum 21 fluctuates, and the space between the peeling member 28 and the heating drum 21 is changed. In some cases, stress is applied to the front and back of the image carrier 1 that is nipped and conveyed. Then, the transport speed of the image carrier 1 may change. Therefore, the liquid absorbing member 103 may be formed of a member having elastic characteristics, for example, an elastic body. In this case, as shown in FIG. 3B, the liquid absorbing member 103 is deformed by the tension of the peeling member 28, and the peeling member 28 comes into close contact with the liquid absorbing member 103. The liquid absorbing member 103
Is shown by a two-dot chain line. As described above, when the liquid absorbing member 103 is made of an elastic body, there is a step between the surface of the liquid absorbing member 103 and the surface of the heating drum 21 other than the portion where the liquid absorbing member 103 is provided. Even at this time, due to the tension of the peeling member 28, the range in which the peeling member 28 faces the heating drum 21, specifically,
In the range from the position indicated by reference numeral C to the position indicated by reference numeral D in the figure, the heating drum 21 is completely adhered. Thus, it is possible to prevent a difference in the transport speed of the image carrier 1 between the peeling member and the heating member, and prevent a slip from occurring.

When the liquid absorbing member 103 has been used for a long period of time, the liquid absorbing member 103 is deteriorated and its absorption performance is reduced. Ingredients such as activators and in-flight dust,
In addition, stains such as an image forming substance such as toner removed from the image holding member 1 may adhere. If the liquid absorbing member 103 is continuously used in such a state, there is a possibility that the liquid cannot be sufficiently absorbed or that the image absorbing member 1 is stained by the liquid absorbing member 103.

Therefore, it is desirable that the liquid absorbing member 103 is detachably attached to the heating drum 21. FIG. 4 is an explanatory diagram for explaining an example of the liquid absorbing member 103 provided detachably on the heating drum 21 in this manner. In the illustrated example, the liquid absorbing member 103 is
Holding member 1 made of a material having good heat conductivity such as metal
04 is fixed to the holding member 10 by bonding or the like.
A handle 104a is provided on the front side of 4. A rail portion 105 is provided on a portion of the heating drum 21 to which the holding member 104 is attached, and the rail portion 105 is provided on a surface of the holding member 104 on the heating drum 21 side.
And a rail receiving portion (not shown) that engages with the rail.
When removing the liquid absorbing member 103 fixed to the holding member 104 from the heating drum 21, the operator holds the handle 104 a and slides the handle 104 a in the direction of arrow E to remove the liquid absorbing member 103. Can be. When a new liquid absorbing member 103 is attached, the new liquid absorbing member 103 can be attached to the heating drum 21 by sliding in the direction of arrow F. As described above, by providing the liquid absorbing member 103 so as to be detachable from the heating drum 21, if the absorbing performance of the liquid absorbing member 103 is reduced, or if dirt such as dust or image forming substance adheres, the liquid absorbing member 103 may be removed and replaced with a new one. Can be replaced or cleaned. Therefore, it is possible to prevent the liquid from being unable to be sufficiently absorbed or to prevent dirt from adhering to the image holding member 1 due to the deterioration of the absorption performance of the liquid absorbing member 103.

Further, by providing a pressure member for squeezing out the liquid absorbed by the liquid absorbing member 103 from the liquid absorbing member 103, the liquid absorbing member 103 can be dried quickly. FIG. 5 is an explanatory diagram showing an example employing such a configuration. In this example, a pressure roller 107 is provided as a pressing member that presses a portion of the surface of the heating drum 21 other than a region facing the peeling member 28. Press roller 107
Is heated by the urging force of the pressure spring 106.
1 is exerting a pressing force. The pressing roller 1
As the material of the surface of 07, for example, metal, rubber, cloth products and the like can be used. And the heating drum 21
When the liquid absorbing member 103 reaches the pressurizing portion by the pressing roller 107 by the rotation of, the liquid absorbed by the liquid absorbing member 103 by the pressing force is squeezed out. As a result, the amount of liquid held by the liquid absorbing member 103 decreases, and the liquid absorbing member 103 can be quickly dried by the heat of the heating drum 21. Also,
It is also possible to remove dirt and the like accumulated on the surface of the liquid absorbing member 103 by the pressing roller 107. The squeezed liquid is discharged out of the machine by, for example, a fan installed in the machine.

The example shown in FIG.
Is an example in which the heater drum 21 is always in contact with the heating drum 21. However, the heater drum 21 may be configured to be in contact with or separated from the heating drum 21 at a predetermined timing, or may be configured to vary the contact pressure.

The evaporation of the liquid from the liquid absorbing member 103 is mainly caused by the heating drum 21 and the peeling member 28.
This is performed in a region other than the facing region (hereinafter, referred to as a non-facing region). Therefore, by installing a fan or the like as a discharging means for discharging steam to the outside of the apparatus near the non-opposed area, it is possible to prevent dew condensation and temperature rise in the apparatus. (Hereinafter, margin)

When the image carrier 1 enters the peeling section and comes into contact with the liquid absorbing member 103 which has absorbed the liquid,
There is a possibility that the liquid from the liquid absorbing member 103 may re-adhere or stains may adhere. Therefore, in the peeling section in the present embodiment, the image carrier 1 that has entered the peeling section
Is configured so as not to come into contact with the liquid absorbing member 103. Hereinafter, this configuration will be described with reference to FIG. FIG. 6 is an explanatory diagram for explaining the relationship between the installation position of the liquid absorbing member 103 on the surface of the heating drum 21 and the contact position with the image holding member.

Length is set. For this reason, when the first image carrier 1a is ejected from the peeling section and the second image carrier 1b enters the peeling section, the tip of the second image carrier 1 becomes the surface of the heating drum 21. Of the first image carrier 1 exactly matches the position where the leading end of the first image carrier 1 is in contact. Then, the second image holding member 1 comes into contact with the heating drum 21 so as to overlap with the area of the heating drum 21 which is in contact with the first image holding member 1. As described above, the surface of the heating drum 21 corresponding to the interval between the image carriers 1 does not come into contact with the image carrier that has entered the peeling section. Therefore, as shown in FIG. 6, the heating drum 2 corresponding to the distance between the image carriers 1
