本発明は、例えば複写機、ラインプリンターファクシミ
リ等の定着部等に用いるローラ即ち弾性定着ローラに関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roller, ie, an elastic fixing roller, used in a fixing section of a copying machine, a line printer facsimile, etc., for example.
（従来の技術）
複写機等の定着部は通常第３図のような構成になってお
り、加熱定着ローラ（１０）と加圧定着ローラ（１１）
の間を、トナー（１２）の転写されたコピー紙（１３）
を通すことによって熱（通常は１７０℃〜２００℃）と
圧力によってコピー紙に画像を定着するという方式が、
安全性、経済性々どの点から一般に採用されている。(Prior Art) The fixing unit of a copying machine or the like usually has a configuration as shown in Fig. 3, which includes a heating fixing roller (10) and a pressure fixing roller (11).
Copy paper (13) with toner (12) transferred between
This method uses heat (usually 170°C to 200°C) and pressure to fix the image on the copy paper by passing it through.
It is generally adopted due to its safety and economic efficiency.
この場合、加熱定着ローラ（１０）としては、アルミニ

６）に硬度が数十度の耐熱ゴム（一般にはシリコーンゴ
ムカ用イられる）を数域の厚みに被覆したもの（この被
覆を（１７）で示す）が用いられる。In this case, the heating fixing roller (10) is made of metal such as aluminum, ceramic, or heat-resistant plastic, and the surface of the roller core (14) is coated with fluororesin to improve the release properties of the toner. A pressure fixing roller (15) coated with several tens of micrometers, or coated with silicone rubber or fluorine rubber with a thickness of 18 or less (these coatings or coatings are indicated by (15)) is also used as a pressure fixing roller (15).
1) is a roller base material (1) made of aluminum or the like.
For 6), a heat-resistant rubber (generally silicone rubber is used) having a hardness of several tens of degrees is coated with a thickness of several ranges (this coating is shown as (17)).
尚、分離爪（１８）はコピー紙の巻き付きを防止するた
めのもので、幅敗笥のものが４〜５箇所に取り付けられ
ており、通常は加熱定着ローラ側のみであるが、高速機
や両面コピーの場合には第６図のように加圧定着ローラ
側にも分離爪（１９）が収り付けられる。なお・第３図
中（２０）は定着画像、（２３）はヒータである。The separation claws (18) are used to prevent the copy paper from getting wrapped around the copy paper, and are installed in 4 to 5 locations. In the case of double-sided copying, a separation claw (19) is also installed on the pressure fixing roller side as shown in FIG. Note that (20) in FIG. 3 is a fixed image, and (23) is a heater.
上記のこのようなゴムローラは、コピー紙が巻き付いた

破損しにくく、寿命的にも数倍のびることは記載の内容
の通りである。When the above-mentioned rubber roller is wrapped around the copy paper, it may be gouged out by the separating claw and become damaged, rendering it unusable. For this purpose, the outer layer of the roller base material is covered with a porous body of tetrafluoroethylene resin, as described in JP-A-60-179770, which the present applicant previously developed and applied for a patent. There is a roller impregnated with silicone rubber and cured, and as described, this roller is less likely to be damaged by separation claws and has a lifespan several times longer.

The adhesion between the layers is insufficient, causing peeling problems during use.
This was one of the causes of instability in terms of durability.
なお弗素樹脂をコーティングしたローラは弾性かないた
めコピーの画質が悪い、定着が劣る、紙しわが生じやす
い等の欠点がある。Note that rollers coated with fluororesin are not elastic, so they have drawbacks such as poor copy image quality, poor fixing, and paper wrinkles.

Then, on the outside of the roller base material, tetrafluoroethylene resin (polytetrafluoroethylene) (PTFE) and tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA) or tetrafluoroethylene-hexafluoropropylene copolymer Laminating two or more layers of porous material of a mixture with (FEP),
It is characterized by having a coating layer formed by impregnating and curing a heat-resistant rubber such as silicone rubber or fluorine rubber in the porous portion of the fired product.

理由も同様である。In addition, in the second invention, the meaning of scattering PFA or FEP powder is the meaning that the powder does not form a sheet, and this is because the pores of the porous body are placed in communication between the layers. This is because it is necessary for impregnating heat-resistant rubber into a porous body. The reason for using a PFA or FEP network is also the same.
