い。However, in order to cope with end use where heat resistance is required as in recent years, when heat resistant toner having poor fixability is used, or when a heat roller type fixing machine is used, high speed is achieved with limited electric power (heat quantity). In the case of copying, the most preferable method is web cleaning, which has a high residual toner removal efficiency.

ある。A web made of 100% aramid of aramid short fibers and aramid fibrid has heat resistance and is preferable when used at high temperature, but has a drawback that the surface of the fixing roller or the photoconductor roller is abraded due to its hard material.

く損なう欠点をもっていた。A web obtained by thermocompression-bonding a dry or wet non-woven fabric composed of aramid fibers and unstretched polyester fibers with a calender roll is considered to be most suitable for this purpose. Since sticking occurs, fluffing occurs and it is easy to cut the sheet due to the roller being caught. Therefore, the calendering speed must be reduced to a very low speed, which has a drawback that the productivity of the web is significantly impaired.

【００１０】本発明においてアラミド繊維の好ましい例
として、ポリ（メタフェニレンイソフタルアミド）短繊

ましくない。As for the single yarn fineness, a finer fiber is generally preferred because a soft web can be obtained. From the viewpoint of industrial applicability, generally, the single yarn fineness is preferably 0.5 to 4.0 denier. Fibers thinner than 0.5 denier are impractical due to poor productivity. If it exceeds 4.0 denier, not only is the web hardened, it is easy to cause roller wear, but the number of fibers constituting the web is reduced, resulting in poor cleaning performance.
【００１２】本発明においてポリエステル繊維の好まし
い例はポリエチレンテレフタレート繊維、ポリブチレン
テレフタレート繊維である。In the present invention, preferred examples of the polyester fiber are polyethylene terephthalate fiber and polybutylene terephthalate fiber.

It is desirable to keep it at 335 to 1.350. 1.335
Unstretched yarns having a specific gravity of less than 3 are industrially difficult to produce and thus are problematic for practical use.

構成繊維の本数が減り接着性を損うので好ましくない。The preferable range of the single yarn fineness of the unstretched polyester fiber is 0.8 to 6.0 denier. Unstretched polyester fibers of less than 0.8 denier are expensive because they are difficult to industrially produce. When it exceeds 6.0 denier, the number of fibers constituting the web decreases and the adhesiveness is impaired, which is not preferable.

くない。The third component, that is, the stretched polyester fiber, which coexists with the aramid fiber / unstretched polyester fiber, is
The specific gravity measured by the method described below must be in the range of 1.38 to 1.41. A drawn yarn having a specific gravity of less than 1.38 cannot prevent hot roll fusion of an undrawn yarn even if it is made to coexist. A drawn yarn having a specific gravity of more than 1.41 is not preferable because it is difficult to industrially produce and the flexibility of the web is impaired.

０．５〜３．０デニールである。The preferred single yarn fineness of the drawn polyester fiber is 0.3 to 4.0 denier, and particularly preferred is 0.5 to 3.0 denier.

The web composition of stretched polyester fiber is 40 by weight.
It should be -60 / 30-45 / 10-30.
If the aramid fiber content is less than 40% by weight, the heat resistance of the cleaning web is impaired. 200 ° C if it exceeds 60% by weight
Even in a temperature range of near actual use, the web is not softened and the surface of the fixing roller or the like is damaged, which is not preferable.

への融着発生があり好ましくない。If the composition of the unstretched polyester fiber is less than 30% by weight, the thermal adhesiveness is insufficient, and not only the mechanical strength of the web is lowered, but also fluff and fallen fibers are generated, which is not preferable. If it exceeds 45% by weight, fusion to a hot roll occurs, which is not preferable.
