Therefore, in recent years, the photoreceptor has been developed towards thinning, but the photoreceptor will be consumed by grinding and the like every time an image is formed by cleaning the blade, so the thinner the photoreceptor is, the lower the image forming frequency will be. End of life, resulting in shortened photoreceptor life
[0014] 3. With colorization, the burden on the photoreceptor increases
In addition, the user has to replace and replenish the toner more frequently than the photoreceptor replacement frequency, which consumes more than the photoreceptor, which has traditionally been a burden on the user.

Embodiment Construction
[0095] In the present invention, the photoreceptor and the toner accommodating portion, which has previously accommodated toner in order to replenish toner to the developing device, are integrated and replaceable as a photoreceptor toner assembly. agent. Compared with the consumable parts of other image forming mechanisms, if the photoreceptor and the toner, which are consumables with high replacement frequency, can be integrated and replaced at the same time, the economic burden on the user and the waste of the recycling labor of the manufacturer can be reduced. There is no impact on the environment, and the user's inconvenience and trouble for the convenience of replacement can also be eliminated. Although the replacement frequency of both is high, it is difficult to correspond to the replacement timing without any processing due to differences in the life of the photoreceptor and the consumption of the toner. In order to further improve the completeness of the assembly, it...

The present invention provides an image carrier toner unit and an image forming apparatus, which can prevent the disadvantages caused by market demand in recent years, have little burden on users, manufacturers and the environment, and consider the convenience of replacement by users. In this image carrier toner assembly, an assembly formed integrally of an image carrier, a support member, and a toner storage unit is detachable from a device on which the assembly is mounted, and the support member is integrally formed with the image carrier. , supporting the image carrier; the toner storage unit is integrally formed with the support member, and stores toner for visualizing a latent image on the image carrier. In this way, the convenience of the user's replacement work can be improved, and the running cost due to the replacement can be suppressed. In addition, since useless replacement of each imaging component is not performed, the burden on the environment is also reduced.
Description
technical field [0001] The present invention relates to an image-carrying body toner assembly and an image forming apparatus, in particular, to a replaceable image-carrying body toner assembly, and an image forming apparatus such as a copier, a printer, and a facsimile equipped with the image-carrying body toner assembly. forming device. technical background [0002] Conventionally, as in Patent Document 1, there has been proposed a so-called process cartridge in which at least one of a developing device, a charging device, and a cleaning device as an image forming mechanism is integrally formed with a photoreceptor and is detachable from an image forming apparatus. [0003] Such a process cartridge has an advantage that replacement and / or maintenance can be easily performed by the user without relying on a professional service person. That is, the process cartridge integrates the photoreceptor, the container of the cleaning device supporting the photoreceptor freely rotata...
