2. Description of the Related Art Conventionally, an electrophotographic copying type image forming apparatus forms an electrostatic latent image on a uniformly charged photosensitive member of an image carrier by exposure, optical writing, or the like. Is visualized using, for example, a two-component developer in which a magnetic carrier and a toner are mixed, or a one-component developer in which the two are integrated, and the visible image is transferred to a transfer material. To obtain a copy. Such an image forming apparatus of the electrophotographic copying system removes coarse particles and the like in a toner as a developer through a screen at the final stage of an image forming process, thereby forming an image on the image. A technique for preventing the occurrence of abnormal images such as sand-like fog, vertical streak-like unevenness, and transfer failure is known (see Japanese Patent Application Laid-Open No. 5-293443). 2. Description of the Related Art In an image forming apparatus, a cleaning device is provided for removing a toner remaining on an image carrier such as a photoreceptor or an intermediate transfer member after a visible image is transferred onto transfer paper. Furthermore,

Recycled toner which is held or held, moves or agitates the recycled toner, and presses it by sandwiching it between the inside of the cylindrical part of the sieve part, crushing it and pushing it out of the cylindrical part of the sieve part and also preventing clogging of the sieve part The separation of the recycled toner is promoted by the idler having a specific gravity larger than the specific gravity of the agglomerated toner. In this case, the occurrence of clogging of the filter means is further reduced, and paper dust and toner aggregates are more reliably removed from the recycled toner. Thus, it is possible to provide a recycle toner classifying apparatus that saves resources and further reduces running costs while avoiding the occurrence of abnormal images while providing effective use of resources by reusing more recycled toner. Became. That is, since the specific gravity of the mover is larger than the specific gravity of the toner, pulverization, extrusion, clogging prevention, and stirring effects can be ensured. According to the thirty-fourth aspect, the separation of the cylindrical filter means for separating the recycled toner discharged from the recycled toner discharge means is freely movable with respect to the cylindrical inner peripheral surface of the sieve portion of the separation promoting auxiliary means. The metal that prevents the clogging of the sieve part while moving or agitating the recycled toner and pressing it by sandwiching it between the inside and the cylindrical part of the sieve part is pressed and crushed and pushed out of the cylindrical part of the sieve part. Since the separation of the recycled toner is promoted by the mover, the function of pulverizing the aggregated toner mass and pushing it out from the sieve by the weight and hardness is further increased, the separation rate is improved, and the mesh filter is simply arranged and vibrated. As compared with the case where the toner is provided, the occurrence of clogging of the filter means is further reduced, and paper dust and toner aggregates are more reliably removed from the recycled toner. By reusing many recycled toners, the generation of abnormal images is further avoided while providing effective use of resources, and a recycled toner classifying device that saves resources and further reduces running costs can be provided. . According to the thirty-fifth aspect of the present invention, the separation of the recycled toner discharged from the recycled toner discharging means by the cylindrical filter means can be freely performed on the cylindrical inner peripheral surface of the sieve portion of the separation promoting auxiliary means. Non-magnetic that moves or stirs the recycled toner and presses it by sandwiching it between the inside of the cylindrical part of the sieve part, crushing it and pushing it out of the cylindrical part of the sieve part and preventing clogging of the sieve part Since the separation of the recycled toner is promoted by the idler of the material, even if a magnetic substance such as a carrier enters, it is discharged from the sieve without adsorbing to the inductor, and the vibration is imparted simply by arranging the mesh filters. As compared to the case, clogging of the filter means is further reduced, and paper dust and toner aggregates are more reliably removed from the recycled toner. Generation of the test while abnormal image by reuse of Kurutona the effective use of resources is also further avoided, resource saving, has become possible to provide a recycled toner classifying device achieve further down the running costs. Since the mover is made of a non-magnetic material, even if a magnetic material such as a carrier enters, the effect of being discharged from the sieve portion without being absorbed by the mover can be exhibited.

According to the thirty-sixth aspect of the present invention, the separation of the recycled toner discharged from the recycled toner discharging means by the cylindrical filter means is performed on the cylindrical inner peripheral surface of the sieve portion of the separation promoting auxiliary means. The recycle toner is held freely so that the recycled toner can be moved or agitated and sandwiched between the inside of the cylindrical part of the sieve part and pressed, crushed and pushed out of the cylindrical part of the sieve part and also prevent the clogging of the sieve part Since the separation of the recycled toner is promoted by the idler having the guiding member, the arrangement of the idler is stabilized, and the filter means is clogged as compared with the case where the mesh filter is simply arranged and vibration is applied. Is further reduced, paper dust and toner agglomerates are more reliably removed from recycled toner, and more recycled toner is reused. Abnormal images while subjected to effective use of resources is also further avoided, resource saving, has become possible to provide a recycled toner classifying device achieve further down the running costs. According to the invention of claim 37, the separation of the recycled toner discharged from the recycled toner discharging means by the cylindrical filter means is performed by collecting the recycled toner discharged in the filter means in the cylindrical shape of the sieve portion.
