本発明は、ＰＰＣ複写機、レーザービームプリンター、
ファクシミリ等の定着装置に用いる離型剤塗布ローラに
関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to PPC copying machines, laser beam printers,
The present invention relates to a release agent coating roller used in a fixing device such as a facsimile machine.
（従来技術）

後述第４図参照）、ローラのどちらか一方あるいは両方

するが、この為の装置の一つとして本出願人は次の様な
離型剤塗布ローラを開発した。(Prior Art) In a fixing device that burns the toner onto the copy paper by passing the toner (4) transferred onto the copy paper (3) between a heat fixing roller (1) and a pressurized elastic roller (2),
(See Figure 4 below), a mold release agent (usually silicone oil is used) is applied to one or both of the rollers, and the applicant has developed the following mold release device as one of the devices for this purpose. Developed a coating roller.
即ちこの離型剤塗布ローラは、トナー像を形成した複写

ある。That is, this release agent application roller applies a release agent to the fixing roller of a fixing device that heats and fixes a toner image by passing the copy material on which a toner image has been formed between a fixing roller and a pressure roller that are pressed against each other. This coating device forms a porous layer of fluororesin porous membrane on the surface of a hollow roller with holes penetrating the surface, holds a release agent in the hollow part of the roller, and seals both ends. This is used as the coating roller, and this is used as the mother of the fixing roller.
The release agent is applied to the fixing roller through the fluororesin porous membrane layer by the centrifugal force acting on the release agent when the release agent is brought into contact with the fixing roller in the linear direction and rotated in accordance with the rotation of the fixing roller.
上記は次のような利点がある。The above has the following advantages.
■ 離型剤の塗布量は弗素樹脂多孔質膜の孔径、膜厚と
離型剤の粘度に関連する為、同じ離型剤と多孔質膜でも
膜の巻き故を変えることで簡単に離型剤の塗布量を制御
できる。即ち弗素樹脂多孔質膜としてどのような孔径、
膜厚、気孔率のものも利用でき塗布量に応じて巻き数を
変えるだけで良い。■ The amount of mold release agent applied is related to the pore diameter and film thickness of the porous fluororesin membrane and the viscosity of the mold release agent, so even with the same mold release agent and porous membrane, it is possible to easily release the mold by changing the way the membrane is wound. The amount of agent applied can be controlled. In other words, what kind of pore size does the fluororesin porous membrane have?
Films with different thicknesses and porosity can be used, just change the number of turns depending on the amount of coating.
■ 高速回転になるほど離型剤に働く遠心力が大きくな
り従って弗素樹脂多孔質膜からの離型剤の透過量も増す
。従ってローラが高速回転、即ち高速の複写機になるほ
ど多量の離型剤の塗布が可能である。■ The higher the rotation speed, the greater the centrifugal force acting on the mold release agent, and therefore the amount of permeation of the mold release agent from the fluororesin porous membrane increases. Therefore, the faster the roller rotates, that is, the higher the speed of the copying machine, the more release agent can be applied.
（発明が解決しようとする問題点）
しかし乍ら従来のこの種離型剤塗布ローラは、中空部も
多孔層も同じ粘度の離型剤を用いていた。(Problems to be Solved by the Invention) However, in this type of conventional mold release agent coating roller, a mold release agent having the same viscosity is used in both the hollow portion and the porous layer.
この様に従来の塗布ローラは、同じ粘度の離型剤（オイ
ル）を用いていたため、初期のｉ型剤の塗布量が多く、
これがコピー紙の離型剤じみの原因となっていた。また
これを抑えるため離型剤の粘度を高くすると、数万枚で
離型剤の吐出量が少なくなり、トナーのオフセット（二
重写し）の原因となった。In this way, since conventional application rollers used mold release agents (oil) of the same viscosity, the initial amount of I-type agent applied was large;
This caused release agent to bleed onto the copy paper. Furthermore, when the viscosity of the release agent was increased to suppress this, the amount of release agent ejected decreased after tens of thousands of sheets were printed, causing toner offset (double copying).
上記に鑑み本発明はこのような問題点を解消するため開
発されたものである。In view of the above, the present invention has been developed to solve these problems.

に蓋をして、離型剤塗布ローラを作る。A porous fluororesin membrane (12) (preferably a polytetrafluoroethylene resin porous membrane manufactured by Custom Denko Corporation, trade name Boaflon) is attached to the surface of the roller (1) processed into such a shape by heating and pressing as shown in Figure 1. Wrap it to a thickness of 0.05 to 5 m+, and after impregnating it with a mold release agent as described in the special notes of this application below, put a mold release agent (silicone oil X13) into the hollow part of the metal roller and cover both ends of the roller. Make a release agent application roller.

表面に離型剤を塗布するものである。The release agent coating roller (15) is used by bringing it into contact with the generatrix direction of the fixing roller (1) and rotating the coating roller (15) to separate it from the fluororesin porous membrane onto the fixing roller surface. This is to apply a molding agent.

５０〜５００μｍまで離型剤の粘度に応じて自由に選択
できる。The fluororesin porous membrane can be freely selected to have a pore diameter of 0.1 to 10 .mu.m and a film thickness of 50 to 500 .mu.m depending on the viscosity of the mold release agent.
また弗素樹脂多孔質膜をローラに巻きつける方向は定着

Ａ以下であることが望ましい。The above is the same as before except for the special notes mentioned above,
In particular, in the present invention, the fluororesin porous membrane layer (12) is pre-impregnated with a mold release agent having a higher viscosity than the PtI type agent to be put into the hollow part, and more preferably, the hollow part is filled with a mold release agent. It is desirable that the viscosity of the emulsifying mold release agent be equal to or lower than the viscosity A of the mold release agent impregnated into the porous layer.
