からの排出トナーを回収するトナー回収装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toner collection device, particularly to an image forming apparatus such as an electronic copying machine, a laser beam printer, a facsimile receiver, etc. The present invention relates to a toner collection device that collects toner.
第１図は画像形成装置の一種で娶る電子複写機の概要を
示すもので、１は像担持体である感光ドラムで導電層、
光導体層１表面絶縁層を順に重ね九三層構成からなる。FIG. 1 shows an overview of an electronic copying machine, which is a type of image forming apparatus. 1 is a photosensitive drum which is an image bearing member, and a conductive layer,
The photoconductor layer 1 has a 93-layer structure in which surface insulating layers are sequentially stacked.
この感光ドラム１は矢示方向に回転しつつ一次帯電器２

掻き取られ搬送ヌクリュ９によって装置手前側に運ばれ
トナー回収容器１０（鎖線水）に回収される。Next, while the image light is being projected, the primary charge is removed by an AC charge remover 3, which has a polarity opposite to that of the secondary charger 2, and then uniformly exposed to light by a lamp 4, resulting in a static charge depending on the projected image light. Greatness is formed. This electrostatic latent image is developed by the developing device 5, transferred onto the p-transfer paper P by the transfer device 6, and fixed, thereby completing the copying. On the other hand, the toner remaining on the photosensitive drum 1 is scraped off by the blade 81 of the cleaner 7, transported to the front side of the apparatus by the conveyor screw 9, and collected in the toner collection container 10 (dashed line water).

れている。Normally, when the toner collection container is full of toner in the toner collection device, the toner overflows and contaminates the inside of the machine, or the toner is not discharged and gets clogged in the cleaner device, causing trouble. In order to prevent this, a detection means is provided for detecting that the toner is full (1:9).

。FIG. 2 shows an example of the detection means, in which a rung 12 and a sensor 13 that receives the light and generates a signal are disposed facing each other on the side surface of a transparent toner collection container 11. Then, there is toner rattling inside the toner collection container 11.
When the light from the lamp 12 passes through the window 14 of the main body of the machine, this is detected by a change in the signal of the sensor, and at the same time the copying operation of the main body of the machine is stopped.
そこで、容器１１を装置から取出して中のトナーを捨て
、再び装置にセットすれば、コピー動作は可能となる。Therefore, if the container 11 is removed from the apparatus, the toner inside is discarded, and the container 11 is placed in the apparatus again, the copying operation becomes possible.

ナーをばらまき機械内を汚してしまうことになる。However, with the detection means configured as described above, the light from the lamp 12 reaches the force sensor 13 even when the toner recycling container is not set, so that a copying operation is possible. Therefore, if a copying operation is performed in this state, the toner will be scattered inside the machine and the inside of the machine will become dirty.
