イルが浸透されている。 In the figure, 1 is a shaft, which is a roller-shaped iron core. The length of this shaft 1 is approximately the same as the length in the longitudinal direction of a fixing roller (not shown), and a temperature sensor felt 2 is provided at a location corresponding to the location of the temperature sensor of the fixing roller.
However, claw felts 3a and 3b are attached to locations corresponding to the contact locations of the peeling claws of the fixing roller. These felts 2, 3a, and 3b are impregnated with silicone oil.
本実施例に係るオイル塗布装置を複写機の定着
部に配備すると第２図の通りとなる。 When the oil applicator according to this embodiment is installed in the fixing section of a copying machine, the result will be as shown in FIG.
図中、４が定着ローラーを構成する上ローラ
ー、５が定着ローラーを構成する下ローラーであ
り、該上ローラー４側には上記軸１がそのフエル
ト３ａが接合すべく固定されている（他のフエル
ト３ｂ，２も同様であるが隠れて見えない）。 In the figure, 4 is an upper roller constituting a fixing roller, 5 is a lower roller constituting a fixing roller, and the shaft 1 is fixed to the upper roller 4 side so that its felt 3a can be joined (other The felts 3b and 2 are similar, but are hidden and cannot be seen).
こうして、上記軸１の回転により部分的にシリ
コンオイルが塗布される。 In this way, the rotation of the shaft 1 causes silicone oil to be applied partially.
次に本考案の他の実施例に係る定着ローラーへ
のシリコンオイル塗布装置を第３図に掲げる。 Next, a device for applying silicone oil to a fixing roller according to another embodiment of the present invention is shown in FIG.
同図において６は板金であり、湾曲形状を成し
ている（長手辺が紙面より向こう側へ屈曲してい
る）。そして、該板金６の長手辺と他の長手辺の
３点を接続すべくフエルト７が接着されている。
もちろん、該フエルト７にはシリコンオイルが充
分に浸透せしめられている。 In the same figure, 6 is a sheet metal, which has a curved shape (the long side is bent away from the plane of the paper). A felt 7 is bonded to connect the long side of the sheet metal 6 and the other long sides at three points.
Of course, the felt 7 is sufficiently impregnated with silicone oil.
本実施例に係るオイル塗布装置を複写機の定着
部に配備すると第４図の通りとなる。 When the oil applicator according to this embodiment is installed in the fixing section of a copying machine, the result will be as shown in FIG.
図中、８が定着ローラーを構成する上ローラ
ー、９が定着ローラーを構成する下ローラーであ
り、該上ローラー８側には上記板金６がそのフエ
ルト７が接合すべく固定されいる。 In the figure, 8 is an upper roller constituting a fixing roller, and 9 is a lower roller constituting a fixing roller. The sheet metal 6 is fixed to the upper roller 8 side so that its felt 7 can be joined.
こうして、上記板金６のフエルト７を一端から
他端へ移動させて部分的にシリコンオイルを該上
ローラーの限定領域に塗布する。 In this way, the felt 7 of the sheet metal 6 is moved from one end to the other to partially apply silicone oil to a limited area of the upper roller.
〈効果〉
以上の様に本考案の定着ローラーへのシリコン
オイル塗布装置によれば、
シリコンオイルの塗布される部分が削減され
たので経済的に有利となる。<Effects> As described above, the device for applying silicone oil to the fixing roller of the present invention is economically advantageous because the area to which silicone oil is applied is reduced.
フエルト部分に付着したトナーが固まつてロ
ーラーを傷つける危険性がシリコンオイル塗布
部分が縮少された分少なくなり定着ローラーの
寿命が延びる。 The risk of toner adhering to the felt portion hardening and damaging the roller is reduced because the silicone oil applied area is reduced, extending the life of the fixing roller.
