Copying is performed by forming an electrostatic latent image on the outer peripheral surface, attaching toner to the electrostatic latent image to form a toner image, and transferring this to copy paper or the like. Since toner remains on the outer circumferential surface of the photosensitive drum after the copying, it is necessary to remove this residual charged toner, and this removal is performed using a cleaning blade. This cleaning blade is shown in FIG.

われる。[Problems to be Solved by the Invention] In the cleaning blade 1 having the above-described structure, the blade member 3 is pressed against the photosensitive drum 4, so that the attachment of the blade member 3 is limited to part a (see Fig. 3). ), a peeling force based on the pressure contact of the blade member 3 acts, causing a problem in that the blade is easily peeled off from there. That is, as shown in FIG. 4, the blade member 3 is attached to one side edge of the metal plate-shaped holding member 2, and one side edge of the metal plate-shaped holding member 2 is attached to the rounded portion 5. Therefore, there is a problem that the part corresponding to this part does not adhere sufficiently and is easily peeled off. To explain in more detail, the metal plate-shaped holding material 2 is generally punched out by press working, so that one side edge along the longitudinal direction inevitably forms a rounded part 5 due to sagging, as shown in FIG. , and the part on the opposite side is the ridge part 5.
Become a. In this case, the rounded portion 5 and the raised portion 5a
Polishing cannot be applied to the plate-shaped retaining material 2 with the rounded part 5 as described above because the dimensional accuracy will deteriorate and the mounting accuracy will decrease accordingly. The blade member 3 is bonded to one side edge of the blade member 3. In particular, in the cleaning blade l having the above-described structure, it is important to increase the precision in mounting the blade member 3.
If the installation is not accurate, the blade 1 may wear unevenly and the cleaning effect will be significantly reduced, or in extreme cases, the blade 1 and the photosensitive drum 4 may not come into contact with each other partially or completely. This results in the problem that no toner scraping effect can be obtained. For this reason, the metal plate-shaped holding member 2 (pressed product) is used as is without being subjected to any polishing process that would impair its accuracy. However, a sufficient adhesion effect cannot be obtained on the rounded portion 5 as described above, leading to a phenomenon in which the blade member 3 peels off from there during use. Two types of film-like hot melt adhesives are overlapped and bonded under heat and pressure.

グ効果が得られなくなるという難点を生じる。In this case, as shown in FIG. 6, the surface tension of the adhesives 6 and 6a creates a wedge at the interface between the adhesive 6 and the adhesive 6a and the interface between the metal plate-shaped holding material 2 and the adhesive 6a. A problem arises in that voids 7 are formed and the adhesion is not sufficient. In particular, such a wedge-shaped gap 7 is largely formed in the rounded portion 5 on one side edge of the metal plate-shaped holding member 2, which causes the blade member 3 to separate from the above-mentioned portion during use, causing a failure. However, the problem arises that a sufficient leaning effect cannot be obtained.

A plate-shaped holding material is provided for bonding the other side edge of the soft blade member to one side edge of the soft blade member with an adhesive layer, and the adhesive layer has a two-layer structure, and the first adhesive layer is attached to the plate-shaped The holding member is formed with a rounded portion on one side edge side, and the second adhesive layer is formed with the rounded portion between the first adhesive layer and the plate-shaped soft blade member.

When a plate-shaped soft blade member is overlaid and bonded on top of the rounded part with a second adhesive (primer layer), no wedge-shaped voids will be formed in the rounded part, as in the conventional case, and the board will be damaged during use. The inventors have discovered that peeling of the shaped soft blade member does not occur, and have arrived at the present invention.
つぎに、本発明を実施例に基づいて詳しく説明する。Next, the present invention will be explained in detail based on examples.

るブレード部材３のこの部分からの剥離が生じない。FIG. 1 shows an embodiment of the invention. The metal plate-shaped holding material 2 of the cleaning blade 10 is a press-processed product, and a first adhesive N (primer layer) 10a is formed on one edge of the cleaning blade 10 so as to wrap around the rounded portion 5. ing. Then, a second adhesive 111 is formed on the upper side of the curved part 5 so as to surround the rounded part 5, and the adhesive I
The plate-shaped soft blade member 3 is firmly adhered to the metal plate-shaped holding member 2 by s 10 a and 11. In this case, since the rounded portion 5 is completely covered with the first adhesive layer 10a, a wedge-shaped gap does not occur at the interface between the first adhesive layer tOa and the plate-shaped holding material 2 as in the conventional case. Furthermore, since the second adhesive layer 11 is formed on the first adhesive N 10 a in the above state so as to wrap around the rounded part 5, both the adhesive layers 10 a, 11 No wedge-shaped voids are formed between the two. Therefore, the rounded portion 5
Sufficient adhesion is maintained in this area, so that the blade member 3 does not peel off from this area during use.

設定することが効果の点で好ましい。The first adhesive layer 10a can be formed by applying a solvent-type resin adhesive (in solution form) using spraying or capillary action, and drying. In this case, it is preferable to use the above-mentioned solvent type adhesive with a viscosity of about 1 to 10 centimeters, and in particular, the thickness of the first adhesive layer 10a formed after application is 10 to 100 μm. From the viewpoint of effectiveness, it is preferable to set the temperature so that the

効果の点て好適である。Further, the second adhesive layer 11 is formed using a film-like hot melt adhesive such as a polyurethane adhesive. In this case, the melt viscosity at the time of heating and pressurization (melt viscosity at 150 to 170°C) is 1×
From the viewpoint of effectiveness, it is preferable to use a material with a void size of about 10 3 to 5×10′.

ブレード部材が剥離するというような事態を生じない。The cleaning blade having such a structure has an adhesive layer portion that adheres the plate-like soft blade member 3 and the metal plate-like holding member 2, especially the adhesive on the rounded part 5 at one side edge of the metal plate-like holding member 2. Since wedge-shaped voids are not formed in the layer portions, sufficient adhesion is maintained even in the rounded portions 5. Therefore, even if a peeling force is applied to the rounded portion 5 when the blade member 3 is pressed against the angry light drum 4, the blade member 3 will not be easily peeled off, and a good adhesion state can be maintained. Therefore, unlike the conventional case, the blade member does not come off during use.

Then, it was coated to a thickness of 10 μm. In this case, the primer was applied so as to completely cover the rounded portion of the plate-shaped holding material. Note that in Comparative Example 2, no primer was applied. Next, a film hot-melt adhesive was temporarily fixed by hot pressing to one side edge portion of the plate-shaped holding member on which the first adhesive layer was formed after the above application. Next, this was placed on a predetermined heating plate (150 to 160°C) of an adhesive press machine, and the urethane rubber blade was stacked on top of it in a predetermined state, and heated under pressure for 1 to 2 minutes. Glued. As a result, the desired cleaning blade was obtained.
