[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording material on which an image is formed by an image forming apparatus such as a copying machine, a facsimile, a printer, a printing machine, or by a human means using a writing tool, a stamping tool, or the like. More particularly, the present invention relates to an image forming material removing apparatus for removing an image forming material for forming an image from an image forming material and regenerating the recording material, and more particularly to an image forming material removing apparatus for reducing a deterioration in quality of the recording material after removing the image forming material. It concerns the device.

[0002]

2. Description of the Related Art In recent years, printers, copiers, and printing machines using image forming methods such as an electrophotographic method, a thermal transfer method, an ink jet method using hot melt ink, and a printing method have become widespread, and a large amount of paper has been used. in use. However, since paper, which is generally used as a recording material on which images are formed, is made from pulp obtained from wood, consuming a large amount of paper leads to deforestation and deterioration of the global environment, In recent years, it has become a social problem. Further, there is a problem that the recording material on which an image is formed by these image forming methods is discarded in a large amount, and it becomes difficult to dispose of the refuse.

As a transparent sheet as a recording material for an overhead projector (OHP), a plastic film such as a polyester film or an acetate film is generally used as a base material. The raw material of the film is synthesized from fossil materials such as petroleum,
It is manufactured from wood like paper, and it is preferable to use a large amount of a transparent sheet as a recording material for an overhead projector (OHP) from the viewpoint of protection of petroleum resources and protection of the global environment. Absent. Also, O
In the case of an HP sheet, when the paper is processed with a shredder, the wear of the shredder blade is remarkable.
There is a problem that the recording material processed because of mixing with the sheet cannot be reused. For this reason, conventionally, the OHP sheet is often discarded as it is,
There is also a problem in keeping confidentiality of the image information formed on the P sheet.

As a means for solving these problems, an image forming substance removing apparatus which removes an image forming substance adhering to a recording material to enable reuse of the recording material has been widely put into practical use. Have been. Among them, a liquid supply device for impregnating or applying an image removal accelerating liquid to a recording material, and an adhesive force greater than the adhesive force between the surface of the recording material and the image forming material can be exerted on the image forming material. A belt-like peeling member, and a peeling device that peels off the image-forming material from the recording material by pressing and separating the belt-like peeling member from the recording material while heating the surface of the recording material to which the image-forming material is attached. An image forming substance removing apparatus including a discharge conveying device that discharges and conveys the recording material having passed through the peeling device has been widely used.

However, in this type of image forming substance removing apparatus, when a synthetic paper or an OHP sheet having a coating layer made of a resin or the like on the surface of a base material is regenerated, the surface of the synthetic paper or the OHP sheet is brought into contact with a conveying member. There is a problem that the quality is degraded by generating traces and rubbing traces with the conveyance path (hereinafter, the contact traces and the rubbing traces are referred to as rubbing traces and the like). In particular, when the above-mentioned rubbing traces and the like occur on a transparent recording material such as an OHP sheet, the rubbing traces and the like appear as shadows in a projected image when projected by a projector, so that they cannot withstand actual use. Failure occurs. Note that, when a plurality of recording materials are continuously processed, the above-mentioned rubbing marks and the like are easily generated.

Further, in an image forming substance removing apparatus provided with an inside-out device for turning over a recording material passed through the above-mentioned peeling device while applying pressure, the recording material is warped (hereinafter referred to as curl). However, there is a problem that the quality is reduced. The curl of the recording material causes a stack failure of the recording material on a paper discharge tray of the image forming material removing device, and also causes the recording material to be removed in the image forming device when reused in the image forming device. This causes a problem of causing a jam.

[0007]

The inventors of the present invention have conducted intensive studies on the cause of the above-mentioned rubbing marks and the like, and as a result, the following phenomena have been found. That is, the recording material impregnated or coated with the image removal accelerating liquid as a liquid generates steam by being heated in the peeling device. Even after the recording material is discharged from the peeling device, the recording material is transported while generating steam by the residual heat. Therefore, the water vapor stays on the path downstream of the peeling device in the transport direction of the recording material ( Hereinafter, this route is referred to as a downstream transport route.) When the steam is left as it is, the water vapor is condensed on the members in the downstream transport path as the temperature decreases, and becomes water droplets. Further, each member of the downstream transport path may be in direct contact with the recording material,
Water drops are applied. Then, the water droplets adhered on each member in the downstream conveyance path in this way come into contact with the recording material conveyed on each member, and are re-transferred onto the recording material, and It becomes rubbing traces.

Further, regarding the cause of the curl,
As a result of intensive studies made by the present inventors, it was found that the phenomenon was as follows. That is, the recording material heated in the peeling device is easily deformed by increasing the temperature. Then, the recording material that is easily deformed is easily deformed and curled by being given a pressure when passing through the above-mentioned reversing device.
