【発明の詳細な説明】
本発明は乾式現像を行う電子複写装置において、トナー
粉体［象を記録ソート上に定着させるトナー粉体像定着
装置に離型液を供給する装Ｈに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device H for supplying a release liquid to a toner powder image fixing device for fixing toner powder on a recording sort in an electronic copying apparatus that performs dry development. .
トナー粉体像が形成された記録シートヶ、一対の回転体
により回動軸方向において挾圧し、記録ソートを搬送し
ながら熱もしくは圧力、または熱と圧力との双方により
、トナー粉体像を記録シートに定着するトナー粉体像定
着装置は良く知られている。The recording sheet on which the toner powder image has been formed is clamped in the rotation axis direction by a pair of rotating bodies, and the toner powder image is transferred to the recording sheet using heat or pressure, or both heat and pressure while conveying the recording sort. Toner powder image fixing devices are well known.
このようなトナー粉体像定着装置における問題点として
は、定着時に、記録シートが、トナー粉体像に接触する
方の回転体に巻きついたり、トナーの一部が上記回転体
の表面に付着し、これが新たなトナー粉体像の定着の際
に新たな記録シートに付着して、画像を汚す所謂オフセ
ット現象が生じたりする点？あげることができる。上記
回転体へのトナーの付着または定着装置の定着機能を低
劣化させる原因ともなる。Problems with such toner powder image fixing devices include that during fixation, the recording sheet may wrap around the rotating body that comes into contact with the toner powder image, and some of the toner may adhere to the surface of the rotating body. However, when a new toner powder image is fixed, this adheres to a new recording sheet, causing a so-called offset phenomenon that stains the image. I can give it to you. This may cause toner to adhere to the rotating body or cause deterioration of the fixing function of the fixing device.
このような問題点な解決する方法としては、トナー粉体
像に接触する回転体の表面に、シリコン油などの離型液
ケ外部から供給する方法や、上記回転体をＲＴＶシリコ
ンゴム（室温加硫シリコンゴム）で被Ｎし、定着時に、
ＲＴＶノリコンゴム内部例含浸されている離型液が、回
転体の表面に滲出するよう（でする方法が提案されてい
る。Methods to solve these problems include a method of supplying a mold release liquid such as silicone oil from the outside to the surface of the rotating body that comes into contact with the toner powder image, or a method of supplying a mold release liquid such as silicone oil from the outside to the surface of the rotating body that contacts the toner powder image, and a method of supplying the above-mentioned rotating body with RTV silicone rubber (room temperature temperature). When fixing,
A method has been proposed in which the release liquid impregnated inside the RTV Noricon rubber oozes out onto the surface of the rotating body.
しかし、離型液を外部から供給する場合、離型液の供給
量を適量に制御することが困難であり、供給過多になり
がちであり、一部が滴下ｔ、４、複写装置内の部材を汚
したりするほか、離型液が記録７−トに付着し、得られ
た複写に書き込みをする場合などにインクをはじいたり
するようになる欠点がある。However, when the mold release liquid is supplied from outside, it is difficult to control the supply amount of the mold release liquid to an appropriate amount, and it tends to be oversupplied. In addition to staining the recording paper, the release liquid also adheres to the recording sheet, causing it to repel ink when writing on the resulting copy.
また、離型液を含浸させたＲＴＶシリコンゴムで被覆し
た障１転体な用いる場合、内部に離型液が存在する間は
問題はないが、内部の離型液が尽きると、離型効果も失
なわれ、前述の問題が生じ、一般に、回転体の寿命が短
かいという欠、Ｑがある。In addition, when using a barrier coated with RTV silicone rubber impregnated with mold release liquid, there is no problem as long as the mold release liquid is present inside, but when the mold release liquid runs out, the mold release effect becomes less effective. This causes the above-mentioned problem, and generally there is a drawback that the life of the rotating body is short.
本発明の目的は、この↓うな欠点を除去した、トナー粉

ている。The mold release liquid storage tank 52 stores therein a mold release liquid 6 such as silicone oil, and one end of the contained mold release liquid 6 is immersed in this mold release liquid 6. The transmission member 56 is configured to transmit the light to the roller 51 that is in contact with the other end of the transmission member 56 by capillary action.
伝送部材５６を形成する材料は、離型液に対して耐性を
有し、毛管現象を惹起しうるものであれば何でも良い。The transmission member 56 may be made of any material as long as it is resistant to the mold release liquid and can cause capillary action.
例えばフェルトなどは、好適なものの一つである。For example, felt is one of the suitable materials.
ローラー５１は、図示されない保持体に↓り回動自在に
保持され、定着ローラー１と常接している。The roller 51 is rotatably held by a holder (not shown) and is in constant contact with the fixing roller 1 .

、ローラー５１に対し伝送部材５６？接触させ、あるい
は離隔きせることができる。The other end of the operating rod 55 is locked to a crank 56. Therefore, when the crank 56 is rotated in the direction of the arrow by a drive mechanism (not shown), the rod 52 is moved to the support shaft 52 when the mold release liquid is supplied.
The transmission member 56 can be brought into contact with or separated from the roller 51 by this rocking movement.
さて、離型液供給時には図示の如く伝送部材５６はロー
ラー５１と接触し、これによって離型液収容タンク５２
かも９着ローラー１へいたる離型液伝送路が形成される
。Now, when the mold release liquid is supplied, the transmission member 56 comes into contact with the roller 51 as shown in the figure, and thereby the mold release liquid storage tank 52
A release liquid transmission path leading to the roller 1 is formed.
