【発明の詳細な説明】 産業上の利用分野 この発明は、複写機に用いる熱定着ロールに関するもの
で、更に述べると、電子複写機用熱定着ロールおよびそ
の製造方法に関するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat fixing roll used in a copying machine, and more specifically to a heat fixing roll for an electronic copying machine and a manufacturing method thereof.
従来の技術 電子複写機には、着色トナーと樹脂を主成分とする乾式
現像剤を支持体上に加熱定着するために、熱定着ロール
が用いられる。2. Description of the Related Art In an electronic copying machine, a heat fixing roll is used to heat and fix a dry developer containing a colored toner and a resin as main components on a support.
この熱定着ロールは、円筒状絶縁性支持体の表面にマス
キング線材をねじ状に巻き付け、それらの表面に発熱抵
抗材を溶射して発熱抵抗体層を形成した後、前記線材を
除去して溝を形成しそれらの表面にテフロン（登録商
標）層を形成することにより製造されるが、この溝は、
隣接する発熱抵抗体層の相互間を絶縁する関係上その相
互間が完全に切れていること、即ち、その溝の底辺が直
接絶縁性支持体に接触していることが要求される。In this heat fixing roll, a masking wire rod is wound around the surface of a cylindrical insulating support in a screw shape, and a heating resistor material is sprayed on these surfaces to form a heating resistor layer, and then the wire rod is removed to form a groove. Are formed and a Teflon (registered trademark) layer is formed on their surface.
In order to insulate the adjacent heating resistor layers from each other, it is required that they are completely cut off from each other, that is, the bottom of the groove is in direct contact with the insulating support.
その上、溝幅は、ロールの表面温度の均一化を図り、か
つ、テフロン（登録商標）使用量を少なくするためでき
るだけ狭く形成することが要求される。そこで、この溝
幅を狭くするため、細いマスキング線材、例えば、直径
0.3mmの金属線を使用することが考えられる。In addition, the groove width is required to be formed as narrow as possible in order to make the surface temperature of the roll uniform and reduce the amount of Teflon (registered trademark) used. Therefore, in order to narrow this groove width, a thin masking wire, for example, a diameter
It is conceivable to use 0.3 mm metal wire.
しかし、絶縁性支持体は、溶射により形成される関係上
その表面には、第５図に示すように凹凸があるので、金
属線３を巻き付けると、その表面と金属線３との間に隙
間２が生じる。そのため、絶縁性支持体の表面に発熱抵
抗材を溶射すると、前記隙間２にも発熱抵抗材が入り込
み第６図に示すように、溝４の底面に発熱抵抗体層５が
形成されて隣接する発熱抵抗体６、７が電気的に接続す
る。However, since the insulating support has irregularities on the surface due to being formed by thermal spraying, as shown in FIG. 5, when the metal wire 3 is wound, a gap is formed between the surface and the metal wire 3. 2. Therefore, when the heat generating resistance material is sprayed onto the surface of the insulating support, the heat generating resistance material also enters the gap 2 and the heat generating resistance layer 5 is formed adjacent to the bottom surface of the groove 4 as shown in FIG. The heating resistors 6 and 7 are electrically connected.
従って、この溝４は、絶縁作用を果たさなくなるので欠
陥のある熱定着ロールとなってしまう。Therefore, the groove 4 does not perform the insulating function and becomes a defective heat fixing roll.
そこで、溝４の切れを良くするため、太いマスキング線
材、例えば、直径0.7mmの金属線を使用せざるを得な
い。Therefore, in order to improve the cutting of the groove 4, it is unavoidable to use a thick masking wire, for example, a metal wire having a diameter of 0.7 mm.
発明が解決しようとする問題点 従来例の太いマスキング線材では、第７図に示すように
溝４の切れは良くなるが、溝幅Ｗが広くなり、例えば、
0.7mmとなる。Problems to be Solved by the Invention In the conventional thick masking wire rod, as shown in FIG. 7, the groove 4 is cut well, but the groove width W is widened.
It will be 0.7 mm.
そのため、発熱抵抗体６、７と溝４とにフッソ樹脂を塗
着してテフロン（登録商標）層を形成すると、溝上のテ
フロン（登録商標）層9aが発熱抵抗体６、７上のテフロ
ン（登録商標）層９より薄くなるので、テフロン（登録
商標）層を平坦にするにはテフロン（登録商標）層9aの
厚さに合わせてテフロン（登録商標）層９を研削しなけ
ればならない。Therefore, when a fluororesin is applied to the heating resistors 6 and 7 and the groove 4 to form a Teflon (registered trademark) layer, the Teflon (registered trademark) layer 9a on the groove changes the Teflon (registered trademark) layer on the heating resistors 6 and 7 ( Since it is thinner than the Teflon layer 9, the Teflon layer 9 must be ground to match the thickness of the Teflon layer 9a in order to flatten the Teflon layer.
この時のテフロン（登録商標）層9aの厚さt1が、例えば
60μｍであり、又、テフロン（登録商標）層９の厚さt2
が、例えば、100μｍであるとすると、高価なテフロン
（登録商標）を厚さ40μｍにわたって削り捨てることに
なるので、熱定着ロールの製造コスト高騰の原因とな
る。At this time, the thickness t 1 of the Teflon (registered trademark) layer 9a is, for example,
The thickness of the Teflon (registered trademark) layer 9 is t 2
However, for example, if the thickness is 100 μm, expensive Teflon (registered trademark) is scraped off over a thickness of 40 μm, which causes a rise in the manufacturing cost of the heat fixing roll.
この発明は、上記事情に鑑み、切れが良く溝幅の狭い溝
を得ることを目的とする。The present invention has been made in view of the above circumstances, and an object thereof is to obtain a groove that is well cut and has a narrow groove width.

材料として最適である。Next, a heating resistance material, for example, nichrome, stainless steel, aluminum, aluminum brazing or the like is sprayed onto the insulating layer 11 around which the metal wire 12 is wound by using a spray gun G to form a heating resistance layer 13. This aluminum or aluminum brazing material is extremely suitable as a resistance material because it has a very small change in resistance value over time due to high temperature and is inexpensive.
この溶射により発熱抵抗体層13が所定の厚さd1、例え
ば、d1＝30μｍになった後、金属線12を、抵抗体層13か
ら取り除くと、絶縁層11の表面には、帯状発熱体層13と
溝14が、交互にねじ状に形成される。When the metal wire 12 is removed from the resistor layer 13 after the heat generating resistor layer 13 has a predetermined thickness d 1 of , for example, d 1 = 30 μm by this thermal spraying, the surface of the insulating layer 11 has a band-shaped heat generation. The body layers 13 and the grooves 14 are alternately formed in a screw shape.

となり、発熱抵抗体層15,16は、完全に分離される。At this time, the shape of the cross section of the groove 14 including the axis C in the insulative support 10 is, for example, a rectangle having a length of 30 μm and a width of 0.3 mm, and the heating resistor layers 15 and 16 are completely separated. It
次に、発熱抵抗体層15,16と溝14に、粉体塗装ガンＰに
より、フッソ樹脂または、シリコン樹脂をコーテング
し、附着防止層17を形成する。Next, the heating resistor layers 15 and 16 and the groove 14 are coated with a fluorine resin or a silicone resin by a powder coating gun P to form an adhesion prevention layer 17.
この時、附着防止層17の厚さd2は、例えば、100μｍで
あり、又、溝14上の附着防止層17aの厚さd3は、例え

厚さd2と厚さd3との差は、僅か10μｍであり、第７図の
従来例に比し極端に減少している。これは、溝幅Ｗが、
従来例の約半分になったことに由来する。The difference between the thickness d 2 and the thickness d 3 is only 10 μm, which is extremely smaller than that of the conventional example shown in FIG. 7. This is because the groove width W is
This is because it is about half that of the conventional example.
コーテング終了後、附着防止層17の表面を研削してロー

この発明の実施例は、上記に限定されるものではなく、
例えば、第４図に示すように断面矩形状のマスキング線

For example, as shown in FIG. 4, a masking wire 21 having a rectangular cross section is wound around the surface of the insulating support 10 in a double screw shape,

場合よりも熱伝動率が良い。Therefore, it is possible to form a groove that is well cut and has a narrow groove width. Further, since the strip-shaped heating resistor layer is formed by thermal spraying, the heating resistor layer is in close contact with the surface of the insulating support. Therefore, of the amount of heat generated in the heating element layer, the amount of heat transferred to the support layer side is always constant, so that the amount of heat transferred to the attachment prevention layer side is also always constant. Therefore, the temperature of the heat fixing roll in the length direction can be controlled to easily make the temperature uniform. Furthermore, since the adhesion preventing layer is adhered to the surfaces of the heating resistor and the groove, the heat of the heating resistor is directly transferred to the adhesion preventing layer, so that the heat transfer coefficient is higher than that in the case where an insulator or the like is interposed between the two. good.
