る方法である。An electrophotographic copying machine is equipped with a photosensitive drum having a photoconductor surface layer, and the outer circumferential surface of the photosensitive drum is uniformly charged, and then the outer circumferential surface is exposed to light through the image of the object to be copied. Copying is performed by forming an electrostatic latent image on the outer circumferential surface, adhering toner to the electrostatic latent image to form a toner image, and transferring this to copy paper or the like each time. After the above copying, is there any toner remaining on the outer peripheral surface of the photosensitive drum? Therefore, it is no longer necessary to remove the residual charged toner, and the dust is removed using a cleaning plate. This is shown in FIG. In the figure, ■ is a cleaning blade, which is constructed by attaching a plate-shaped soft urethane resin blade member 4 along the length direction to the lower end of a plate-shaped holding material 3 manufactured by Kinnobu Co., Ltd., which has a flange 2. The member 4 is pressed against the photosensitive drum 5 rotating in the direction of the arrow, and the residual toner (
(not shown). Conventionally, three types of methods have been used to bond the metal plate-shaped holding member 3 and the soft urethane resin blade member 4 in this type of cleaning blade 1. The first method is to use an adhesive, the second method is to use an adhesive tape, and the third method is to use a hot melt adhesive.

Each of the above methods has some drawbacks. That is, in the first method, the soft urethane resin blade member swells and warps due to the solvent contained in the adhesive layer, and a uniform adhesive layer cannot be obtained, making it difficult to achieve high-precision adhesion. I can't. In the second method, since sufficient adhesive strength cannot be obtained, practical strength is not maintained over a long period of time, resulting in the disadvantage that the soft urethane resin blade member peels off during use. The third method has no problem in terms of strength, but it requires bonding the soft urethane resin blade member to the metal plate-shaped holding material by heating, which may cause thermal deformation of the soft urethane resin blade member. Further, there is a drawback that dimensional accuracy is difficult to achieve due to a difference in degree of expansion due to a difference in coefficient of thermal expansion between the metal plate-shaped holding member and the soft urethane resin blade member.

る。Recently, there has been an increasing demand for weight reduction and cost reduction for office equipment in general, and for electrophotographic copying machines in particular, so the above-mentioned soft urethane resin blade member is bonded directly to the casing of the electrophotographic copying machine, etc., instead of to a metal plate-shaped holding material. There is a need to reduce the number of parts and manufacturing processes. In order to meet these demands, it is extremely important to perform bonding with high dimensional accuracy, and as the blade member is mainly made of soft urethane resin as mentioned above, it is easily deformed by heat. , and because there is a difference in thermal expansion coefficient between the casing, etc., instead of the conventional adhesive method,
There is a need for proposals for new methods that can achieve high-precision bonding.

ブレードの製法を第２の要旨とするものである。In order to achieve the above object, the present invention provides a synthetic resin plate-like soft blade member whose one side edge along the longitudinal direction is a cleaning part, and a synthetic resin plate-like soft blade member whose other side edge is a cleaning part. The first aspect is a cleaning blade comprising a plate-shaped holding material provided through an adhesive layer, the adhesive layer being made of a hot melt adhesive containing magnetic powder, and one side along the longitudinal direction. The other side edge along the longitudinal direction of the synthetic resin plate-like soft blade member whose edge serves as the cleaning part and the one side edge along the longitudinal direction of the plate-like holding material are bonded using a hot melt adhesive containing magnetic powder. The second gist is a method for manufacturing a cleaning blade in which the above-mentioned two members are bonded together by overlapping the two members with a film interposed therebetween and heating by high-frequency induction heating to melt the adhesive film.

ようになる。That is, according to the manufacturing method of the present invention, the adhesive film is melted by high-frequency induction heating to bond the synthetic resin plate-shaped soft blade member and the plate-shaped holding material. The holding material itself is not heated at all, and only the adhesive film is heated and melted to exhibit an adhesive effect. Therefore, thermal deformation does not occur in both the members, and highly precise and strong bonding can be achieved in a short time. In addition, the resulting cleaning blade contains magnetic powder in the adhesive layer, and this magnetic powder exhibits a static electricity discharging function, so that static electricity generated during use of the cleaning blade is effectively dissipated through the adhesive layer. well released. Therefore, it becomes possible to avoid the adverse effects of accumulated static electricity.

It is preferable to use iron oxide (ferric oxide). The amount used is 200-2000 P I for hot melt adhesive.
-IR is preferably set within the range, and most preferably within the range of 400 to 1200 PHR. That is, if it is less than 200 PlfR, a sufficient heating effect cannot be obtained in high-frequency induction heating, and at the same time, the electrostatic discharge effect becomes small. On the other hand, 2000 P HR
This is because if it exceeds the amount, the amount of magnetic powder becomes too large and it becomes impossible to finish the hot melt adhesive thinly when forming it into a film. It is preferable for the hot melt adhesive containing such magnetic powder to have a thickness of 200±20 μm from the viewpoint of the heating effect in high-frequency induction heating, but this can be selected as appropriate depending on the object.

よる悪影響を回避することができるようになる。As described above, according to the present invention, the adhesive film is melted by high-frequency induction heating to bond the synthetic resin plate-shaped soft blade member and the plate-shaped holding material. The shape-retaining material itself is not heated at all, and only the adhesive film is heated and melted to exhibit an adhesive effect. Therefore, thermal deformation does not occur in both of the above members,
Furthermore, since both members do not undergo thermal expansion, there is no reduction in dimensional accuracy due to a difference in thermal expansion coefficients, and high-precision, strong bonding can be achieved in a short time. In addition, the resulting cleaning blade contains magnetic powder in the adhesive layer, and this magnetic powder exhibits a static electricity discharging function, so that static electricity generated during use of the cleaning blade is effectively dissipated through the adhesive layer. well released. Therefore, it becomes possible to avoid the adverse effects of accumulated static electricity.
