のである。Detailed Description of the Invention (Industrial Field of Application) The present invention provides a heat fixing roll of a PPC (dry copying machine) and an LBP (laser beam printer) to make the toner and paper peelable on the surface of the roll. The present invention relates to a cleaning roll that is coated with silicone oil that increases the surface of the roll and is used to clean the roll surface without causing scratches.

がある。(Prior art and its problems) Conventionally, cleaning materials and oil coating materials for heat fixing rolls of PPC and LBP include (a) a polyurethane rubber blade, (11) one side of the blade is in contact with the fixing roll, and the other side is in contact with the fixing roll. A combination of oil-coated felt soaked in a silicone oil storage tank; (c) a roll covered with felt, fabric, paper, etc. impregnated with silicone oil;
(d) There are rolls, etc. in which a cylindrical body filled with silicone oil is provided with through holes and the cylindrical body is covered with felt, textiles, paper, or the like.

付き等の問題がある。Generally, PPC, L, which uses a heated fixing roll as a fixing device,
In BP, there are problems such as smearing of copied images due to toner adhering to the surface of the heat fixing roll, and wrapping of paper around the roll caused by resin components of the toner fused to the roll surface.

る。A method for solving these problems is to supply silicone oil, which enhances the releasability of toner and paper, to the surface of the heat fixing roll, and at the same time wipe off the toner and other stains on the roll surface. However, in the case of (a) above, not only is it not possible to remove toner etc. sufficiently, but the next toner adheres on top of the remaining toner, making it harder to peel off the paper, causing it to wrap around the roll, and staining the copied image. There will also be more.

加する。Also, in the case of (b) above, the cleaning effect is not sufficient, and on the contrary, the demerit of increasing the size and cost of the apparatus due to the separation of the oil application and cleaning functions is significant. On the other hand, in the case of (c) and (d) above, in which oil application and cleaning are performed at the same time, the total area of the cleaning portion of felt, fabric, paper, etc. is small, resulting in a shortened maintenance cycle and increased running costs.
又、全クリーニング面積を大きくするにはロール径を大
きくしなければならず、装置が大型化されるという欠点
があった。Furthermore, in order to increase the total cleaning area, the diameter of the roll must be increased, which has the disadvantage of increasing the size of the apparatus.

題点があった。In order to eliminate the above drawbacks, as shown in Japanese Patent Application Laid-Open No. 58-19971, aromatic polyamide fibers and polyethylene terephthalate fibers are made of a winding type pre-impregnated with silicone oil to provide heat resistance. A cleaning roll made of nonwoven fabric has been proposed, but this cleaning roll requires a driving device for the feeding section and the winding section, which poses a space problem in PPC copying machines, etc., which are becoming smaller. At the same time, there was a problem in that it required many processes such as a web forming process, a silicone oil coating process, and a seaming process, making it expensive.

ものである。(Means for Solving the Problems) In order to solve the above problems, the present invention has an integrated structure of a nonwoven fabric cylindrical body with a coarse and dense two-layer structure and a roll core body,
The upper layer of the two-layer structure nonwoven fabric cylinder has a high-density layer made of heat-resistant fibers and heat-shrinkable fibers, and a lower layer has a low-density layer made of heat-resistant fibers. By molding the cleaning roll into one piece by shrinkage, we have solved the problem by creating a cleaning roll with a long life and excellent wiping effect that can sufficiently retain silicone oil and control oil leakage. .

Insert 20
By heat-treating at 0° C. for 10 minutes, the nonwoven cylindrical body is contracted, and the cylindrical body and the roll core are tightened and fixed together to form the cleaning roll of the present invention. When using the above cleaning roll, first seal one end of the roll integrally with a heat-resistant sheet material, then pour silicone oil into the low-density lower layer of the other end, fill it, and seal it together with a heat-resistant sheet material. and use it. Further, the silicone oil may be injected by providing one or more required through holes in the longitudinal direction of the lower layer of the two-layer nonwoven cylindrical body in advance.

ーニングロールを得ることができる。(Function) As described above, the lower layer of the cylindrical nonwoven fabric having a coarse and dense two-layer structure has a low density, so a large amount of silicone oil can be held in a large number of pores formed in the fiber gaps, and a high density can be achieved. The outer upper layer makes it possible to control the amount of silicone oil that flows out, resulting in a longer service life and a cleaning roll that can be integrally molded.
