Description of the Related Art Conventionally, as a fixing device in an electrophotographic copying machine or the like, a dry fixing device, that is, an unfixed powder toner image transferred onto an image support such as paper is applied with a non-adhesive heating roll and elasticity. An apparatus is often used in which heat and pressure are applied to a pressure roll to fuse and fix. In such a fixing device, when toner adheres to and remains on the surface of the heating roll, the copy image becomes dirty due to the offset phenomenon. Therefore, the surface of the heating roll is impregnated with releasing oil such as silicone oil during operation. In order to remove the residual toner and to apply the release oil, the release property of the heating roll is improved and the surface of the heating roll is kept clean.

でも充分とされていた。The frequency of use of electrophotographic copying machines and facsimiles equipped with such a fixing device varies greatly depending on the application. In an apparatus that requires a large amount of image processing at high speed, an oil coating roll having an oil-impregnated surface layer is used as an oil coating member, and release oil is gradually applied to the surface of the oil coating roll from a separately prepared oil tank. There are some that are designed to supply. In order to further simplify the structure of the fixing device, a hollow cored bar is filled with release oil, and the oil-impregnated surface layer is gradually released from the inside through a large number of pores provided in the wall surface of the cored bar. An oil coating roll adapted to supply oil is also used. On the other hand, in a device that requires a small amount of image processing at a low speed, there is a device that uses a non-woven fabric pad impregnated with a release oil as an oil application member, and this is sufficient.

が採用されるに至っている。Recently, however, an apparatus having a high processing speed is required even if the amount of image processing is relatively small. In such a case, the release oil impregnated pad is insufficient in performance as an oil application member. It cannot be used because it does. Therefore, a method of using a so-called disposable oil application member has been adopted, in which an oil application roll having a thick oil-impregnated surface layer is impregnated with release oil in advance and used until the release oil is consumed. There is.

After wrapping etc., wrap an oil permeation suppressive sheet (3) with the desired oil permeability to adjust the leaching speed of the release oil, and fix the end of it with adhesive, and put it in the tank. Further, it was manufactured by immersing it in a release oil such as silicone oil to sufficiently impregnate the release oil and absorb the release oil to remove the release oil excessively attached to the surface.

As (6), a polyamide / polyester mixed paper having oil permeability of 4 and 8 g / cm 2 hr, respectively, is used instead of the polyamide / polyester mixed paper having oil permeability of 16.5 g / cm 2 hr. A roll was formed in exactly the same manner as in Example 1, and was similarly impregnated with silicone oil to obtain an oil coating roll F of Comparative Example 3 and an oil coating roll G of Example 4.

The amount of oil applied was about 8 times that of C. Further, the oil coating roll I of Comparative Example 4 was too large in the amount of oil coating, and the normal copying operation was impossible.
