のに関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a fixing device that fixes an unfixed toner image carried on a recording material through a predetermined process as a permanent image on the recording material. In particular, it relates to one having a release agent coating member.

か普及している。[Prior Art] A toner image fixing device for fixing a toner image on a recording material uses a heating roller 1 having a heater 4 inside as shown in FIG. 6, and a pressure roller 2 in pressure contact with the heating roller 1. Heat roller fixing devices that perform fixing by nipping and conveying a recording material to be supported are in widespread use.

間を延ばすことがてきた。The conventional release agent applicator shown in FIG. 4 has a structure in which a felt 15 impregnated with silicone oil is supported by a support member 20 so as to be in contact with the fixing roller 1. The structure is as follows. Although this device is effective because it can simultaneously apply oil as a mold release agent and clean the surface of the fixing roller 1, the absolute amount of silicone oil contained in the felt 15 is small, which may cause an oil shortage early on. The part of the felt 15 that comes into contact with the fixing roller becomes dirty, which also causes early cleaning failure and requires the felt 15 to be replaced. In contrast, the fifth
A release agent application roller as shown in the figure has been proposed. For example, there is a silicone rubber layer 8 as an intermediate layer on a core made of stainless steel, and a felt layer 9 made of heat-resistant felt is formed on the surface layer, and this felt layer 9 has a viscosity of 1 (1 loOcs silicone oil is uniformly impregnated in the longitudinal direction of the release agent application roller.The release agent application roller contacts the fixing roller 1 and rotates as a result of the application, applying silicone oil to the fixing roller 1. However, in the case of this mold release agent application roller as well, if the silicone oil impregnated into the felt layer is insufficient, it must be replaced, or the replacement interval must be adjusted as much as possible. In order to make the length as long as possible, as shown in Fig. 6, a release agent application roller 3 is made to be able to come into contact with and separate from the fixing roller 1 freely. During times when fixing is not required, such as during standby or during pre-rotation of a copying operation, the release agent application roller 3 is separated from the fixing roller 1, so the amount of release agent discharged is reduced accordingly. This has increased the time it takes to replace them.

にばらつきが生じてしまうという問題があった。[Problems to be Solved by the Invention] However, in the case of the configuration in which the release agent application roller is brought into contact with and separated from the release agent application roller in this way, the posture of the member that holds the release agent application roller is changed when the release agent application roller is brought into contact with the fixing roller. There was a problem in that the contact force was not determined and a predetermined contact force could not be ensured, resulting in variations in the amount of mold release agent applied.

Approximately 15 g of cS silicone oil is uniformly impregnated in the longitudinal direction. This oil application roller has a holding member (holder) at the shaft portion 9A that protrudes from both ends in the longitudinal direction.
It is rotatably held by 14. As shown in Figure 1, one of the bearings on both sides of the holder that holds the core metal of the oil application roller has a slit on the right side of the drawing, and this slit is used to hold the member. The oil coating roller can be expanded from this portion by pushing and pulling the shaft 9A.

っている。As shown in FIG. 1, the holder 14 has a hook-shaped protrusion 14B on the opposite side (right side in the drawing) of a handle 14A for attaching and detaching from the main body, and the oil application roller comes into contact with the fixing roller. The structure is such that there is no risk of the oil application roller jumping out of the holder when the oil application roller is removed.

た板ばねを使用している。Furthermore, a pressure contact spring 20 is provided between the holder 14 and the guide 17 that holds it, in order to ensure a predetermined contact pressure when they come into contact. The spring 20 is a leaf spring bent into a "J" shape to facilitate attachment and detachment of the holder I4.
また、この板ばね20の加圧ポイントは、フック形状の
突起部と、オイル塗布ローラ3と定着ローラ1の当接部
との中間点に位置している。Further, the pressure point of the leaf spring 20 is located at the midpoint between the hook-shaped protrusion and the contact portion between the oil application roller 3 and the fixing roller 1.

掛けている。As shown in FIG. 2, the oil application roller receives a reaction force in the direction shown by the arrow a during contact. At this time, the hook 14B is in a state of being pressed against the cut-and-raised portion because a force is applied to the holder from the leaf spring 20 at a position closer to the hook. Therefore, the force exerts on the oil application roller 3 including the holder in the direction of the arrow, but in order to prevent this, the holder 14 is provided with a hook-shaped protrusion (14-B). Two locations are provided and these are hooked onto the cut and raised portions of the guide member 7.
前述したようにガイド17は17Aを中心に回動自在で
あるが、通常17Bに掛けられているはね21によって
離間する方向に付勢されている。As mentioned above, the guide 17 is rotatable around the guide 17A, but is normally urged in the direction of separation by the spring 21 hooked on the guide 17B.

次に本実施例の定着装置を電子写真装置に用いた場合の
画像形成動作を順を追って説明する。Next, an image forming operation when the fixing device of this embodiment is used in an electrophotographic apparatus will be explained in order.

定着器に送られる。The photosensitive tram (not shown) and the fixing roller rotate simultaneously when the user turns on the copy signal. After the pre-rotation is completed, an optical system (not shown) begins to scan the document and exposes an image onto the photoreceptor drum. Thereafter, the developed image is transferred to a transfer material, which is a recording material, conveyed from a cassette or the like. Then, the transfer material carrying the undetermined image is sent to a fixing device by a conveyance system.

7 rotates counterclockwise around 17A until it hits the stopper. Then, the felt layer 9 of the oil application roller 3 comes into contact with the fixing roller 1. At this time, the holder 14 rotates about a point 15 formed by cutting and bending the hook portion 14-B and the guide 17 as a fulcrum. Then, the relative position of the holder 14 with respect to the guide 17 changes, the leaf spring 20 deforms accordingly, and the oil application roller comes into contact with the fixing roller with a predetermined pressure.

作中の定着装置の動ぎである。After a certain period of time after the oil application roller 3 contacts the fixing roller 1, when the power to the solenoid is turned off, the guide 17 rotates clockwise due to the biasing force of the tension spring 21. The holder 14 and the oil application roller 3 fixed to the guide 17 are connected to the fixing roller 1.
and return to the original standby position. The above is the movement of the fixing device during the image forming operation.

姿勢は正しく得られ所定の当接圧を得ることかてきる。As described above, in this embodiment, the coating rotary body for applying a mold release agent is rotatably supported by a holder, and furthermore, this holder is rotatably supported by a guide member, and this guide is moved. Even if the posture of the guide member is not fixed, the elastic force of the leaf spring 20 can maintain the correct posture of the holder and provide a predetermined contact pressure.

はならないため更に加圧力を安定化することができる。Furthermore, since the fixed end of the leaf spring 20 is arranged near the rotation center 17A of the holding guide 17 when viewed in cross section, the reaction force of the force that presses the oil application roller 3 against the fixing roller 1 is applied to this fixed end. Since it does not become a force that is applied or rotates the holding guide 17, the pressing force can be further stabilized.

Therefore, there is no unevenness in the contact force in the longitudinal direction of the coating rotor.
