Abstract
An image forming apparatus for forming an image in a predetermined image forming region by discharging ink droplets includes an image forming unit for forming an image in the predetermined image forming region, and a suction unit for sucking air including ink mist generated when forming the image by the image forming unit. The suction unit includes at least one suction port provided near the image forming region, and an exhaust path formed below said suction port. The exhaust path includes a slope inclined in a direction crossing a direction of flow of the air including the ink mist sucked into the exhaust path, and an ink collecting portion provided on the slope. According to this configuration, the apparatus collects ink mist generated during recording.

An image forming apparatus for forming an image in a predetermined image forming region by discharging ink droplets, said apparatus comprising:
- an image forming unit for forming an image in the predetermined image forming region;
- and
- a suction unit for sucking air including ink mist generated when forming the image by said image forming unit,
- said suction unit including:
- at least one suction port provided near the predetermined image forming region;
- and
- an exhaust path formed below said suction port,
- said exhaust path including:
- an exhaust port for exhausting air including ink mist sucked from said suction port in a predetermined direction;
- a slope provided at a crossing point of the exhausted air exhausted from said exhaust port and inclined in a direction of flow of the exhausted air;
- and
- an ink collecting portion provided on said slope.
A suction apparatus for sucking air, which includes ink mist generated by formation of an image, near an image forming region of an image forming apparatus, said suction apparatus comprising:
- at least one suction port provided near the image forming region;
- and
- an exhaust path including an exhaust port for exhausting air including ink mist sucked from said suction port in a predetermined direction, a slope provided at a crossing point of air exhausted from said exhaust port and inclined in a direction of flow of the air exhausted from said exhaust port, and an ink absorbing member provided on said slope.
An image forming apparatus for forming an image in a predetermined image forming region by discharging ink droplets, said apparatus comprising:
- an image forming unit for forming an image in a predetermined image forming region;
- at least one suction port provided near said image forming region in order to suck air including ink mist generated in said image forming unit when forming the image;
- and
- an exhaust path formed below said suction port,
- said exhaust path comprising:
- a suction duct into which air including ink mist sucked from said suction port is flown;
- an exhaust port for exhausting the air sucked from said suction port in a predetermined direction;
- a first slope formed in said suction duct, provided at a crossing point of the air exhausted from said exhaust port, and inclined in a direction of flow of the exhausted air;
- a first ink collecting unit provided on said first slope;
- a fan connected to said suction duct in order to suck said air including ink mist from said suction port and to exhaust it through said suction duct;
- a second slope provided at the crossing point of the air exhaustesd from the exhaust port of said fan and inclined in a direction of flow of the air exhausted from said fan;
- and
- a second ink collecting unit provided on said second slope.
