プロセスを完了する。Conventional Structure and Problems Generally, an electrophotographic copying apparatus using an organic photoconductor photoconductor has an endless belt-like photoconductor 61 (hereinafter referred to as
A photoreceptor (referred to as a photoreceptor) is run by a photoreceptor driving drum 51a and a photoreceptor driven roll 51b, the photoreceptor 61 is charged by a charging charger 52, and the photoreceptor 61 is moved from a document table 64 by an exposure device 63 having an exposure lamp 53a and an optical fiber lens s3b. A light image is formed as an electrostatic latent image on the photoreceptor 61, and developed by the developing device 66 to become a visible image. Next, the copy paper 67 is fed from the copy paper cassette 66 by the paper feed roll 68G, and the copy paper 67 is conveyed onto the toner image on the photoreceptor 61 by the transport roll pair 69 and the transfer guide 6o, and the electrostatic The copy paper 67 is adsorbed and transferred by the transfer charger 61.
Transfer the toner image to. As the photoreceptor 61 and the copy paper 67 further advance, the separation claw 62 separates the copy paper 67 from the photoreceptor 61, and the copy paper 67 is guided to the fixing guide 63, where the toner image on the copy paper 67 is formed by the fixing device 64. is fixed and discharged to the paper discharge tray 65. Photoreceptor 61
As the process further progresses, the residual toner after the transfer is removed by a cleaning device 66 having a cleaning blade 66a,
The residual charge on the photoreceptor 61 is removed by the charge removal lamp 67 to complete the copying process.

。With the configuration of the electrophotographic copying apparatus as described above, it is necessary to fuse and connect the ends of the photoreceptor sheet to form an endless belt. In addition, if the length of the belt-shaped photoreceptor is not uniform, it will meander while running, causing charging, exposure, development, and
This method has the disadvantage that accuracy decreases in various processes such as transfer, and only low-quality copied images can be obtained. In addition, when using an endless belt-like photoreceptor, nicks will always occur at the fusion splice, so
During cleaning, the cleaning blade and the cleaning blade rub together violently, resulting in damage to the cleaning blade and poor cleaning of the photoreceptor.Also, since the photoreceptor deteriorates due to wear and other factors, The photoreceptor had to be replaced every time the photoreceptor was used, resulting in a large number of maintenance inspections. Furthermore, since the photoreceptor is shaped like an endless belt, it is difficult to handle. Since the photoreceptor is in the form of an endless belt, it has drawbacks such as difficulty in handling during maintenance and inspection.

る。Structure of the Invention The electrophotographic copying apparatus of the present invention takes out one of the photoreceptor sheets from a photoreceptor cassette that can store a plurality of photoreceptor notes, and records a light image from an original on the photoreceptor sheet. A developing roll is disposed so as to face a developing sleeve of a developing device, and when the photosensitive sheet passes between the developing sleeve and the developing roll, the developing sleeve and the photosensitive member are formed by the developing roll. The gap between the photoreceptor sheet and the photoreceptor sheet is controlled m+ so that this phenomenon occurs, and when the photoreceptor sheet deteriorates and reaches its usable limit, the photoreceptor sheet is collected into the second box of the photoreceptor cassette, and the photoreceptor sheet is collected from the first box. Since the new photoconductor sort is configured to be taken out and used, there is no need to fusion splice the ends of the photoconductor sheet to create an endless belt-like photoconductor, which makes it possible to remove debris from the joints, making cleaning easier. The blade is not damaged, the life of the blade is extended, and the photoreceptor does not meander, so high-quality copied images can be stably obtained. In addition, multiple photoconductors are stored in the photoconductor throat, and a new photoconductor is automatically replaced every time a certain number of photoconductors are used, which reduces the number of maintenance inspections.
′! Furthermore, since the photoreceptor cassette is only replaced when replacing it, maintenance can be easily performed.

るため保守点検の回数を少なくすることができる。Effects of the Invention As is clear from the above description, the electrophotographic copying apparatus of the present invention is a photoreceptor that is equipped with a first box that can store a plurality of photoreceptor sheets and a second box that can collect deteriorated photoreceptor sheets. One photoreceptor notebook is taken out from the first box of the photoreceptor cassette, and the light from the original is formed as an electrostatic latent image on the photoreceptor notebook, and then placed on the developing sleeve of the developer. Developing rollers are disposed to face each other, and when the photoreceptor sheet passes, the developing roller creates a gap between the developing sleeve and the photoreceptor sheet. When the photoreceptor sheet deteriorates and reaches its usable limit, the photoreceptor sheet is collected into the second box of the photoreceptor cassette, and a new photoreceptor sheet is replaced from the first box. Since the sheet is configured to be taken out and used, there is no need to fusion splice the ends of the photoreceptor sheet to form an endless belt-like photoreceptor, making it possible to remove debris from the joints, making cleaning easier. The blade will not be damaged, the lifespan of the blade will be extended, and the meandering of the photoreceptor will not occur, making it possible to stably obtain high-quality copied images.In addition, multiple photoreceptors can be placed in a photoreceptor cassette. Since the photoconductor is stored and a new photoreceptor is automatically replaced every time a certain number of sheets are used, the number of maintenance inspections can be reduced.
捷た、交換時には感光体カセットを取り替えるだけであ
るため、保守を容易にすることができる。When the photoreceptor cassette is torn or replaced, it is only necessary to replace the photoreceptor cassette, which facilitates maintenance.
