【従来の技術】
画像記録装置は、例えば、色分解網点画像データからカラープルーフを作成するのに用いられる。そして、このカラープルーフを作成する方式として様々な方式が提案、実施されており、ＹＭＣ或いはＹＭＣＫの各色の色分解網点画像データを得て、記録材料のインク層と受像材料の受像層とを対面するよう重ね合わせた状態で、この各色の色分解網点画像データに応じた画像状に熱を与えることによりインク層の少なくとも一部を受像層に、この画像状に転写するものがある。この場合、記録材料上に形成されている１０マイクロメートル以下のサイズのドットで構成される網点画像状にインク層の少なくとも一部を受像材料に転写しなければならない。[0002]
[Prior Art]
The image recording apparatus is used, for example, to create a color proof from color separation dot image data. Then, various methods have been proposed and implemented as methods for producing this color proof, and color separation dot image data of each color of YMC or YMCK is obtained, and the ink layer of the recording material and the image receiving layer of the image receiving material In the state where they are superimposed so as to face each other, at least a part of the ink layer is transferred to the image receiving layer in the form of an image by applying heat in the form of an image corresponding to the color separation dot image data of each color. In this case, at least a part of the ink layer must be transferred to the image receiving material in the form of a halftone dot image composed of dots of 10 micrometers or less in size formed on the recording material.

このように、粘着力が強くローラ径の大きな（表面積の広い）回収ローラ２６を設けることにより、回収ローラ２６のみを清掃すれば、圧接する他のクリーニングローラ対２５のクリーニングローラ２５ａ，２５ｂの清掃は不要となり、清掃期間を延長させ、清掃箇所を減らすことができる
この実施の形態では、ロール状の記録材料２及び受像材料３が供給部１０に装填され、搬送部２０にカッターユニット２１を配置しているが、カッターユニット２１を供給部１０に配置してもよく、また、シート状の記録材料２及び受像材料３を供給部１０に装填してもよい。[0031]
As described above, if only the recovery roller 26 is cleaned by providing the recovery roller 26 having a large adhesive force and a large roller diameter (a large surface area), the cleaning of the cleaning rollers 25a and 25b of the other cleaning roller pair 25 in pressure contact is performed. In this embodiment, it is possible to extend the cleaning period and reduce the number of cleaning points. In this embodiment, the roll-shaped recording material 2 and the image receiving material 3 are loaded into the supply unit 10 and the cutter unit 21 is disposed in the conveyance unit 20. However, the cutter unit 21 may be disposed in the supply unit 10, and the sheet-like recording material 2 and the image receiving material 3 may be loaded in the supply unit 10.

回収ローラ２６は、一番粘着力の強い回収ローラ２６が圧接する上側のクリーニングローラ２５ａを、その表面に付着したゴミ、ほこり等の異物を吸い上げて清掃する。清掃されたクリーニングローラ対２５のクリーニングローラ２５ａは、ローラ間に材料がなければ下側のクリーニングローラ２５ｂの表面を清掃することが可能になる。つまり、ゴミ、ほこり等の異物は、クリーニングローラ対２５の下側のクリーニングローラ２５ｂから上側のクリーニングローラローラ２５ａへ、さらに回収ローラ２６の順で移動し、ゴミ、ほこり等の異物は回収ローラ２６に集められることが可能となる。[0041]
The recovery roller 26 cleans the upper cleaning roller 25a, to which the recovery roller 26 with the highest adhesive strength is in pressure contact, by sucking up foreign substances such as dust and dirt adhering to the surface thereof. The cleaning roller 25a of the cleaned cleaning roller pair 25 can clean the surface of the lower cleaning roller 25b if there is no material between the rollers. That is, foreign substances such as dust and dirt move from the lower cleaning roller 25b to the upper cleaning roller 25a of the cleaning roller pair 25 and then to the collecting roller 26, and foreign substances such as dirt and dust are collected from the collecting roller 26. It can be collected into
