点がある。SUMMARY OF THE INVENTION As described above, the heater
When the adhesive is applied to the entire surface of the heater / heater holder contact portion as the bonding method between the heater holders, there are the following problems.
【０００６】１）接着剤がヒータ・ヒータホルダ接着部
からはみ出し、ヒータ表面にでてくる。ヒータ表面には
み出た接着剤は硬化によって突起となったり、潤滑剤と
混ざったりして、正常なフィルム摺動を妨げる。1) The adhesive protrudes from the heater / heater holder bonding portion and comes out on the heater surface. The adhesive that has protruded from the heater surface becomes a protrusion due to curing or mixes with the lubricant, and hinders normal film sliding.

の形状に戻らない。2) After the adhesive is applied in order to cure the thermosetting adhesive in the heater / heater holder bonding step,
Leave for several tens of minutes in a high temperature environment of 0 degrees or more.
The heater holder is deformed by the thermal stress, and is bonded to the heater while maintaining the deformation. When a conventional bonding method is used, the bonding area is large and the bonding layer is thin, so that the bonding force in the shearing direction is too strong, and does not return to the original shape even when cooled after the bonding process.

紙上の未定着トナーを定着させる事ができなくなる。When the heater holder is deformed, it is impossible to apply a uniform pressure in the longitudinal direction of the nip formed by the heater, the film and the pressure roller, and it is impossible to fix the unfixed toner on the transfer paper entering the nip. .

Send the transfer paper. The transfer paper is conveyed together with the film 1 by the above-described pressure roller 2, is heated by the temperature-controlled heater 4, and is pressed in the nip formed between the pressure roller 2 and the heater 4. Thereby, the toner is fixed.

れている。Both electrodes of the heater 4 are contacted by a connector 6 and one connector 6a is connected to a power supply through a temperature control device (not shown). The bundle coming out of the other connector 6b passes through the inner surface of the heater holder 3 and is connected to one end of a thermal fuse 7 as a safety device,
The other end of the thermal fuse 7 is connected to a power supply. The connector 6 b and the thermal fuse 7 are in direct contact with the heater 4 from the respective elongated holes 3 b opened in the heater holder 3.

っかり保持されていなければならない。Therefore, a force is applied between the heater 4 and the heater holder 3 by the connector 6 and the thermal fuse 7 in a direction in which the heater 4 and the heater holder 3 are separated from each other. If the heater 4 and the heater holder 3 are not in close contact, the heater 4 may shift due to poor contact or film sliding, so the heater 4 must be firmly held by the heater holder 3 by bonding.

３ａからあふれない量をそこに塗布される。In this embodiment, the temperature of the contact portion between the heater 4 and the heater holder 3 may be 2 due to the heat generated by the heater 4 in some cases.
Since the temperature may exceed 00 degrees, a silicone-based thermosetting adhesive is used for bonding between the heater 4 and the heater holder 3 in consideration of heat resistance and electrical safety. As shown in FIG. 1, the heater holder 3 has a diameter of about 6 mm and a depth of 0.15 mm.
There are several counterbore holes 3a of about mm, and the adhesive is applied to the counterbore holes 3a in an amount that does not overflow from the counterbore holes 3a.

ダの端部の計６点である。In this embodiment, the position of the counterbore 3a is
There are a total of six points: both ends of a long hole (connector and thermal fuse contact portion) in the heater contact surface of the heater holder, an intermediate portion thereof, and an end of the heater holder.
【００２３】このように、接着剤を数点に分けて塗布
し、かつ、接着剤用のざぐり穴３ａを設けた事によっ
て、接着剤がヒータ４のフィルム摺動面にはみ出る事が
無くなった。As described above, the adhesive is applied at several points and the counterbore 3a for the adhesive is provided, so that the adhesive does not protrude to the film sliding surface of the heater 4.
【００２４】熱硬化性接着剤を硬化させるためには接着
剤を塗布した後ヒータ４・ヒータホルダ３を１００度以
上の環境に数１０分放置しなければならない。In order to cure the thermosetting adhesive, after applying the adhesive, the heater 4 and the heater holder 3 must be left in an environment of 100 degrees or more for several tens of minutes.

ｃ）。そのため、ヒータ４・加圧ローラ２間のニップに
均等な圧がかからず、未定着画像の定着に悪影響を及ぼ
す。At this time, the heater surface of the resin-made heater holder 3 warps in a direction in which the heater surface travels due to thermal expansion (FIG. 4A). At that time, the adhesive is solidified (FIG. 4B), and if there is no deformation in the shear direction of the adhesive, the heater holder 3 is fixed to the heater in a warped shape even after cooling and does not return to the original shape (FIG. 4).
c). For this reason, a uniform pressure is not applied to the nip between the heater 4 and the pressure roller 2, which adversely affects the fixing of the unfixed image.

固定されてしまう。In this embodiment, the counterbore 3a is provided, and an elastic silicone adhesive is used even after bonding. Therefore, even if a lateral force is applied, the bonding layer B is deformed as shown in FIG. The heater holder 3 deformed by the bonding process can return to the original shape after cooling. If there is no counterbore, Fig. 5
Since the adhesive layer is thin (0.05 mm or less) as in b, the deformation is small, and the heater holder is fixed by the adhesive while being deformed.
【００２７】検討によれば、接着層の厚さが０．１ｍｍ
以上であれば、上記のような接着層の変形が起こる。According to the study, the thickness of the adhesive layer was 0.1 mm.
If this is the case, the above-described deformation of the adhesive layer occurs.
【００２８】また、ヒータ４が発熱冷却を繰り返すと
き、ヒータ４・ヒータホルダ３間の膨張収縮によって横
方向の力がヒータ４に掛かるが、前記のように接着層に
よって、その応力は緩和される。Further, when the heater 4 repeats heat generation and cooling, a lateral force is applied to the heater 4 due to expansion and contraction between the heater 4 and the heater holder 3, but the stress is relieved by the adhesive layer as described above.
【００２９】また、前記のようにヒータホルダ３にざぐ

接着ポイントに間違いなく接着剤を塗布する事ができ、
作業性も向上する。Further, by providing the counterbore 3a in the heater holder 3 as described above, the bonding agent can apply the adhesive to the determined bonding point without fail.
Workability is also improved.

穴３ａからはみ出ることがある。<Embodiment 2> In Embodiment 1, the amount of the adhesive applied must be within or within the volume of the counterbore 3a. However, due to the process capability of the adhesive discharger, in the counterbore hole shape of the first embodiment, the adhesive may protrude from the counterbore hole 3a as shown in FIG. 6A.
