Recirculating powdered in grading plant

Abstract

A toner sorting device includes a device for taking in used toner conveyed from an image forming apparatus and conveying the used toner in one direction, and a device for sifting the used toner conveyed from the intake device to separate reusable toner from the used toner. The sifting device includes a tubular sieve for separating reusable toner from the used toner and a device for holding the sieve so that the sieve is rotatable. The sieve has an opening for receiving the used toner conveyed from the intake device to be moved into the sifting device and an opening for discharging the remaining toner separated from the reusable toner and remaining inside the sifting device. The toner sorting device further includes a device for collecting the reusable toner separated from the used toner by the sifting device and a device for collecting the remaining toner discharged from the sifting device. The toner sorting device further includes a device for accelerating sifting of the used toner by the sifting device.

Description

technical field [0001] The present invention relates to a recycled toner classifying device, a process cartridge equipped with the same, a toner storage device, and an image forming device, and more particularly to electrophotographic image forming such as a copier, a printer, a facsimile device, or a combination of the above devices A recycling and classifying device for sorting recovered toner after image forming process in the device, a process cartridge equipped with it, a toner storage, and an image forming device. Background technique [0002] In the past, the electrophotographic copying method is to form an electrostatic latent image on a uniformly charged photoreceptor as an image carrier by exposure and optical writing, etc., using, for example, a toner of a two-component developer that mixes a magnetic carrier and a toner, or both. The integrated single-component developer visualizes the electrostatic latent image, and reproduces the visible image on the reproducti...

Problems solved by technology

[0012] However, in conventional devices that separate recycled toner and other foreign matter using a mesh-like screening device, foreign matter such as paper powder adheres to the mesh-like screening device and clogs the mesh, making it impossible to separate the developer from other foreign matter. Even vibrating the sieve part of the mesh-like screening device has little effect, and it is difficult to promote the separation of recycled toner from other foreign matter. In addition, the aggregated toner is still aggregated and does not become reusable recycled toner. , mostly treated as waste, the effect is not ideal

[0013] A classification device for separating recycled toner and other foreign matter using the above-mentioned conventional mesh-like screening device, and a process cartridge, a toner storage device, and an image forming device equipped with the same also have the following problems: Foreign matters such as foreign matter attached to the mesh-like screening device block the mesh, so that the separation of the developer and other foreign matter cannot be carried out. Separation of other foreign matter. In addition, the agglomerated toner is still agglomerated, and it does not become reusable recycled toner, and is mostly treated as waste.
