As a process, for example, Japanese Patent Publication No. 45-30320, Japanese Patent Publication No. 48-5063, 2% Publication No. 51-341
As described in the above publication, an electrostatic image is formed by a predetermined electrophotographic process on a square-shaped electrophotographic photoreceptor having many minute openings, and light is transmitted through this electrostatic image. The ion flow of the corona can be modulated (r
For example, an image is formed on an image holding member without a photoconductive layer, and then the image is developed and transferred to a recording medium to form a final image. An image holding member used in this electrophotographic process. (3) 1. According to other electrophotographic processes, the toner image formed on the electrophotographic photoreceptor or on the outside of the image without a photoconductive layer is not directly transferred to the recording medium, but is transferred to another light guide. 5: Power is transmitted to an image holding member without a layer, and then the images on the recording body IC) are transferred and fixed from this image holding member. This electrophotographic process is an image holding member used. This process is highly effective for forming color images or high-speed copying. The recording medium is often made of highly flexible materials such as paper or film. For this purpose, rather than transferring the three-color image to a recording medium while accurately aligning the image, it is preferable to transfer the three-color image to an image retention system that can be formed from a material that hardly causes deformation1. If the toner image is transferred to the recording medium using the image holding member, the first color image will be formed with more precise alignment.Also, even when the speed of the object increases, the toner image will pass through the image holding member and be transferred to the recording medium. It is valid that it is transferred to (4)′1/ζ
As another process, an electrical signal is applied to the multi-needle 'Kameyu' to remove the BuC doryu layer. It is a device that can form an electric image and develop it into an image. There are image holding members used in this electrophotographic process.

? J3. The image-holding member that is used for photographing children requires 111 processes such as corona charging treatment, development treatment, and cleaning treatment. It is easily damaged because it is subjected to air and mechanical impact. When the image holding member receives -IJHA scratches, the image η of the formed image is significantly reduced. Therefore, the image holding member whose performance has deteriorated is removed and replaced. Therefore, the image holding member is also a consumable item, and it is easy to manufacture.
They are required to be superior in terms of cost, etc. By the way, among the conventional image holding members, the element that has been most problematic in terms of production, cost, and cost is the support. This support is generally a metal drum. Many metal drums have been used in which molten metal is poured into a mold having an annular opening, and the metal is cooled while passing through the annular opening. This is done by so-called extrusion molding.

However, since the metal drum manufactured in this manner is drawn from a mold, the metal drum ends up being thick and heavy. -t 7t, since the metal drive l formed in this way does not have both end faces, in order to install it in the main body of the copying machine as an image holding member, the metal It needed to be attached integrally to both end faces of the drum, requiring many manufacturing steps. In order to solve this problem, it is effective to form one end surface of the drum continuously and integrally with the circumferential surface of the tram. However, since a large external force is applied to the metal drum of the image holding member in order to drive it to rotate, it is necessary to satisfy both lightness and mechanical strength. Mechanical strength is required for the metal drum part, which receives driving force to maintain rotational drive strength.

Metal drums produced by cold extrusion at Metal Monthly are made by placing the slag (metal piece to be processed) in a mold frame and applying an impact to the slag with a punch, which instantly deforms the slag into a cylindrical shape. It is formed. The metal drum thus formed has a good surface smoothness, and there are concerns about room treatment as secondary processing. In addition, since secondary processing is not required,
A metal dowel with the strength necessary for removing the image holding part, which also requires mechanical reinforcement for secondary processing! , and as a result, it is also possible to form a complete set of drums with a thin wall @1
It is also possible to produce a sexual image holding system. As described above, by using the metal tram 2 formed by the impact cold extrusion process, it is possible to manufacture an image holding member that is easy to manufacture, low in cost, and even for light snacks 1. . 1) A metal tram formed by an expensive cold extrusion process Q) with a closed bottom at one end. This bottom part is opposite to the punched surface of the disk-shaped slag used for forming (corresponds to the surface of !11.) By applying processing for driving the image holding member to the pressure part, it is possible to achieve an extremely MJ bowl. , to? ν It is possible to make a suitable image holder for mounting. In this case, the slag is not placed on the bottom of the concave part of the Z2 type frame, and the bottom surface of the concave part is provided with an uneven surface for driving the image holder. During processing, Mv can be applied at 1 yr.The gold IJ3 drum is immersed in a paint for forming an image-retaining layer, for example, a paint containing photoconductive particles dispersed therein. Even when forming a coating film by pulling up the image removal layer, by immersing it with the bottom part facing downward, the paint will not go around to the inside of the metal drum and contaminate the inner wall of the metal drum. , Manufacture':
Very advantageous.

FIG. 4 is a perspective view of the connecting carrier 8, in which a hook 9 is formed. Since the end face 11 constitutes a part of the metal drum, by using this end face for driving purposes, it becomes completely unnecessary for fastening a separately molded flange. However, such driving processing of the end face is performed by applying the impact cold extrusion force of the metal drum [1] Although the shape can be formed in a separate process from the impact cold extrusion process, as mentioned above, impact cold extrusion force is applied. (2) If it is formed at the same time as the extrusion process, it can be peeled off and processed almost instantly. In fact, this driving process is even easier when forming uneven portions as shown in FIG.

However, since the end face 11 is continuous and integrated with the side part (body) of the metal drum, the material strength of the end face is superior compared to 7 lunges, which is useful for non-hunting. Since it is made of aluminum, a lightweight image holding member can be formed. In addition to the case shown in FIG. 1, the drive processing formed on the end face may have any other shape. For example, a hole for a bearing may be formed in the center. Various metals are appropriately used to form the metal drum, such as aluminum, tin, iron, and brass.

It is also possible to achieve a remarkable effect of low retention: stratification, which is also greatly reduced. With this, the restriction f1'' of collecting used image holding members and reusing them is eliminated, and the so-called disposable image holding members are made disposable.
It is possible to provide an image holding member that is free from scratches.
