いる。2. Description of the Related Art Conventionally, as a method for fixing an image on a transfer paper or the like in the above image forming apparatus, a fixing method using heat, pressure or a combination of both has been proposed. A flash fixing method, a pressure fixing method, a heat roller fixing method and the like can be mentioned. Among these, as a new fixing method, a third fixing method other than the heat roller and the press roller as described in JP-A-3-130149 is used.
A method using a peeling roller as the roll has been proposed. In this method, a peeling roller is arranged on the side of the heat roller, and a fixing belt made of a flexible tubular material consisting of a fluororesin inner layer and a polyimide resin outer layer is hung between the heat roller and the peeling roller, and A method of passing a transfer paper with thermal ink between the press roller and the press roller is adopted.

It also requires a large installation space. Furthermore, in the above method, it is necessary to prepare a cylinder corresponding to the inner diameter of the target tubular object, and the versatility is poor.

Therefore, a polyimide film or the like is suitable as the material of the belt. But,
The polyimide film is usually a film that is difficult to adhere to, and the adhesive is usually inferior in heat resistance to polyimide, so that the excellent heat resistance originally possessed by the polyimide film may not be sufficiently exhibited.

イミドフィルムを用いることが好ましい。The tubular article of the present invention and the method for producing the same will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of the tubular article of the present invention in the vicinity of the joint. As is apparent from FIG. 1, a large number of fine holes for joining are formed at both ends of the plastic film 1, and the resin 3 is filled from both sides (upper and lower) of the plastic film through the fine holes to form the joining portion 2.
I am trying. By joining in this way, the upper and lower resins 3 are integrated to exert an anchoring action, and the joining strength is improved. The plastic film 1 is not particularly limited as long as it has an appropriate mechanical strength capable of withstanding the use such as a fixing belt, but a polyimide film is preferably used from the viewpoint of heat resistance and the like.

It is preferable to set the degree to a certain degree because the resin 3 filled in the joint portion 2 does not influence the obtained tubular article so much. In particular, when a polyimide film having excellent heat resistance is used as the plastic film 1 and a resin having relatively low heat resistance is used as the filling resin 3, in order to prevent the thermal characteristics of the filling resin 3 from affecting. The length (ratio) of the joint is preferably 5% or less.

物に樹脂3の熱特性の影響が発現して好ましくない。As the resin 3 used for the above-mentioned joining portion 2, a so-called B-stage resin that melts at room temperature but loses fluidity after curing, or a resin that melts at high temperature can be used. It may be a resin that is a resin or a thermoplastic resin. From the viewpoint of heat resistance, for example, thermoplastic resins such as polyetherimide, polyether nitrile, and polyether sulfone, and thermosetting resins such as epoxy-based and bismaleimide-based resins can be mentioned. The resin 3 is formed so as to be sandwiched from both sides of the plastic film 1 of the joint portion 2, and this is heated (for example, 320 ° C. in the case of polyetherimide) and pressurized (for example, 0.1 kg / cm 2 or more). The resin 3 is caused to flow to be filled in the fine holes so as to be integrated with each other, whereby the joint portion 2 is formed. Further, it is preferable that the resin 3 is formed in a film shape on both sides of the plastic film 1 from the viewpoint of handleability, and in this case, it is formed in the range of 10 to 200%, preferably 25 to 100% of the thickness of the plastic film 1. To do. If the thickness is less than 10%, resin 3
May not be sufficiently filled inside the fine pores, and the resin 3 may not be integrated, and if the thickness exceeds 200%,
The effect due to the thickness cannot be expected to increase, and conversely, the tubular product obtained is unfavorably affected by the thermal characteristics of the resin 3.
