Problems solved by technology
As mentioned above, it can expand and contract along the length direction with a small force, especially when there is a curved part, the shell wall and the outer shape of the conveying means are in contact to generate friction, and the amount of expansion and contraction is different due to different contact conditions, so it cannot be controlled. Flexibility
[0012] If the downstream end of the powder conveying member does not reach the outlet of the tube, for example, the toner conveying force decreases at the downstream end, and toner clogging occurs at the connection position between the tube and the second tube, causing toner clogging

Embodiment Construction
[0083] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following embodiments, although various limitations are made to constituent elements, types, combinations, shapes, relative arrangements, etc., these are merely examples, and the present invention is not intended to limited to this.
[0084] figure 1 A schematic configuration diagram showing an internal mechanism of a tandem color image forming apparatus. exist figure 1 In , reference numeral 100 denotes the main body of the image forming apparatus, and 200 denotes the image reading device mounted on the main body 100 of the image forming apparatus.
[0085] In the main body 100 of the image forming apparatus, a cyan imaging station 10c, a magenta imaging station 10m, a yellow imaging station 10y, and a black imaging station 10b are arranged in series. In each imaging station, drum-shaped photoreceptors 11c, 11m, 11y, and 11b are respectiv...

The invention provides a powder conveying apparatus with a processing chamber of the powder conveying apparatus and image forming apparatus. The powder conveying apparatus is used for conveying powder including: a part for forming powder conveying channel extends crookedly, and powder conveying member aligned on full length of the part for forming powder conveying channel forms a rotary in the same part to conveying powder and a restriction part, which forms together with the part for forming powder conveying channel and has an outlet for conveying powder by the conveying channel, used for restricting the length of the conveying part aligned on full length of the part for forming powder conveying channel, at the lower end of the part for forming powder conveying channel. Though existing adeviation of the length of powder conveying channel, powder jam like toner and etc. and interference with other parts will not happen.
Description
technical field [0001] The present invention relates to image forming apparatuses such as copiers, printers, facsimile machines and their multifunction machines. Among them, in particular, it relates to an electrophotographic image forming apparatus that directly transfers or indirectly transfers a toner image formed on a photoreceptor through an intermediate transfer body, and records the image on a recording medium such as paper or an OHP film. The present invention also relates to a powder conveying device for conveying powder such as toner in such an image forming apparatus, and a process cartridge provided with such a powder conveying device, which together with the photoreceptor at least makes the cleaning device Integrated, relatively easy to install and detach from the image forming device. Background technique [0002] In an electrophotographic image forming apparatus, after a toner image is transferred to a recording medium, a cleaning device is used to remove the...
