Abstract

PURPOSE:To obtain cut surfaces of cleaning blades as smooth surfaces similar to specularly finished surfaces and to easily obtain the cleaning blades at low cost by forming four blade members in one body, and cutting the body into the individual cleaning blades. CONSTITUTION:While a couple of plate-shaped holding materials 15 are arranged opposite each other across a mold 8, a couple of plate-shaped holding materials 15 are arranged across a mold 9, and the molds 8 and 9 are sandwiched between both U-shaped pieces of the molds 6 and 7 to assemble a molding metallic mold. Urethane resin liquid is injected into the cavity 14 formed of the molds 6-9 and set to form blade members. This obtained molding is cut with a sharp cutting blade and then cut surfaces are smooth surfaces similar to specularly finished surfaces. Consequently, the metallic molds are reducible in cost and the cost of the cleaning blades can be reduced.

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, applying 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. In the figure, 1
is a cleaning blade, and a thick inner plate-shaped blade member 4 made of soft urethane resin is attached to the tip of a metal plate-shaped retaining member 3 with a flange 2 so that the length direction of the plate-shaped retaining member 3 is aligned. The tip portion is embedded in the blade member 4. As shown in FIG. 8, this cleaning blade 1 presses the blade side of the blade member 4 against the photosensitive drum 5 rotating in the direction of the arrow, and slides the lower area of the plate surface A against the photosensitive drum 5. to scrape off residual toner (not shown). This kind of cleaning blade is generally
Using a left and right split mold, which has a cavity for casting the soft urethane resin blade member 4,
It is manufactured by inserting the tip of the plate-shaped holding material 3 into the cavity of the mold, injecting a molding material for soft urethane resin into the cavity, molding, and then removing the mold. There is. The cleaning blade thus obtained is used in the state shown in FIG. 8, but at that time, the frictional force between the blade member 4 and the surface of the photosensitive drum 5 becomes a problem. That is, when the frictional resistance between the two increases, it is necessary to rotate the photosensitive drum 5 against the frictional resistance, so it becomes necessary to increase the output of the drive motor (not shown). The resistance causes wear or damage to the surface of the photosensitive drum 5, resulting in a decrease in the quality of the copied image.

[Problems to be Solved by the Invention] For this reason, conventionally, a mold of a molding die corresponding to one plate surface A (see FIG. 8) of the blade member 4 that comes into pressure contact with the photosensitive drum 5 and the end surface B adjacent thereto. The surface is mirror-finished and the above-
The plate surface A and end surface B were finished to be smooth. However, doing so not only causes an increase in the cost of the molding die and the cleaning blade, but also requires complicated maintenance work to keep the mirror surface in good condition at all times. Furthermore, there was a manufacturing problem in that the use of a mold release agent was restricted because it was a major factor in deteriorating the mirror surface.

When manufacturing a cleaning blade using the above-mentioned mold, a set of two plate-shaped holding materials 1 are
5 are placed facing each other, and at the same time, two pieces I are placed through the fourth mold 9.
A plate-shaped holding material 15 of Mi is arranged, and in that state, the third and fourth molds 8 and 9 are placed on the first and second molds 6 and 7.
Assemble the mold by inserting it between the two U-shaped pieces. Next, a urethane resin liquid is poured into the cavity 14 formed by the first to fourth molds 6 to 9 and cured to form a blade member. Then, by demolding the obtained molded product, a set of two plate-shaped blade members 10.11 and 12.13 are brought into contact with each other, as shown in FIG.
A molded product with a plate-shaped retaining material 15 formed integrally with two sets of sets and the front end surfaces of both sets abutted against each other is obtained. Next, the molded product obtained in this way is cut from the abutting portions of the tip ends of both sets with a razor-sharp cutting blade, as shown by the dashed line B, and then the separated sets of two pieces are cut. By cutting the plate-shaped blade members 10.11 and 12.13 from the joint of the mutual plate surfaces with a razor-sharp cutting edge as shown by the dashed line A, a leaning blade as shown in FIG. 3 is obtained. is obtained. in this case,
The cut surface (-plate surface) A of the soft urethane resin blade member 10 of the cleaning blade is a smooth surface that is almost the same as the mirror-finished surface, and the cut surface (the abutting surface of the tip end surface) B is also the cut surface A. It becomes a smooth surface similar to . Therefore, as shown in FIG. 7, when this cut surface A is brought into pressure contact with the outer peripheral surface of the photosensitive drum, the smoothness of the cut surface provides good frictional resistance.

As described above, according to this embodiment, the molded product is cut with a razor-sharp cutting edge as shown by the dashed lines A and B shown in FIG. 2, and the cross sections A and B are mirror-finished. Because it is formed as smooth as the surface, there is no need to mirror-finish the surface of the mold as in the past, which reduces mold costs, reduces the amount of maintenance work, and reduces separation. It also becomes possible to obtain the effect of expanding the degree of freedom in the use of molding agents.

In addition, as another method of manufacturing a cleaning blade, a first mold 6 and a second mold 7 having a U-shaped cross section as shown in FIG. A molded product (the one shown in FIG. 2 with the plate-shaped holding material 15 removed) is made by injection. Next, the obtained molded product is cut along the chain lines A and B in FIG. 2 to make four blade members 10, 11, 12, and 13, and the plate-shaped holding material 15 is bonded to these using an adhesive or the like. There is a method of obtaining a leaning blade as shown in FIG. This method can also produce the same effects as the above embodiment.

As described above, this invention uses a special molding die,
A molded product with a plate-like retainer is made by combining two sets of individual plate-like blade members with their plate surfaces in contact with each other, and the tip ends of both sets are combined, and the molded product is In order to manufacture four cleaning blades by cutting from the plate surface joining part of the two plate-shaped soft blade members in each set and the abutting part of the tip ends of both sets, the cut surfaces are all mirror-finished. It becomes a smooth surface that is almost the same as the surface. Therefore, it is possible to use a mold that has no mirror surface at all as a molding die, which significantly reduces the cost of the mold, and at the same time, it is possible to eliminate the conventional maintenance work for the mirror surface. It also becomes possible to expand the degree of freedom in the use of mold release agents.
