Abstract
Inside the body of an image forming device, first to fifth electric charge providers are mounted in a first location out of a path of an air flow to the suction unit caused by the action of the suction unit, and a sixth electric charge provider is mounted in a second location through which external air flows in the body caused by the action of the suction unit. Each electric charge provider emits charges in ambient air to cause ultrafine particles floating in the ambient air to clump together.
Claims16
An image forming device of an electrophotographic type comprising:
- a fuser thermally fusing a toner image on a sheet;
- a body containing the fuser;
- a suction unit sucking air from the inside of the body;
- and
- an electric charge provider emitting electric charges in ambient air to cause ultrafine particles floating in the ambient air to clump together, the electric charge provider being mounted in either or both of first and second locations inside the body, the first location being at least one region out of a path of an air flow to the suction unit caused by the action of the suction unit, the second location being at least one region through which external air flows into the body due to the action of the suction unit.
