The present disclosure relates to an image forming apparatus including an exhaust duct collecting particulates and the exhaust duct.
In an image forming apparatus, particulates, such as an ink or a toner, may be floated and scattered inside the apparatus. In order to collect the floated particulates, the image forming apparatus includes, for example, a fan, an exhaust duct and a filter. In the image forming apparatus, an air inside the apparatus is sucked by a fan, guided to the filter by the exhaust duct and cleaned by the filter, and then, ejected outside the apparatus.
As one example of the image forming apparatus, an inkjet printing apparatus is configured to include a noise silencer removing an ink particle with a filter. Inside the noise silencer, a baffle wall isthe image forming apparatus is configured to include a developing device to which a floated toner collecting device. The floated toner collecting device has a sucking duct having a plurality of toner catching protruded parts inside. Each toner catching protruded part is protruded from an upstream side end to a downstream side end in an air current direction in the sucking duct and upward from a bottom wall face in the duct. The toner catching protruded part has a difference recessed to the bottom wall face in the duct at the downstream side end.
However, in the above-mentioned one example's image forming apparatus, in order to make the baffle wall function as the filter, it is necessary to configure a plurality of the baffle walls so as to individually
