An image forming apparatus includes a fuser unit which includes a heat roller and a pressure roller; a duct which is formed in a long shape in a direction along an axis of the heat roller, is disposed in the vicinity of the fuser unit along the axis of the heat roller, and is exhausted by an exhaust fan which is provided on one end side in a long-side direction; an exhaust port which is opened to a first side wall of the fuser unit side of the duct and causes the fuser unit and the duct to communicate with each other; and a planar filter which is attached to an inner wall surface of the duct. The filter includes a filter base material having an irregular surface shape in which ditches and convex portions are alternately disposed; and a frame which is bonded to both ends orthogonal to an irregularity direction of the filter base material, the convex portion of the filter base material protrudes from the frame, and the convex portion of the filter base material is bonded or stuck to the inner wall surface.

Image forming apparatus including a duct filter having corrugated surface shape

A multi-function printer includes a fuser unit which includes a heat roller and a pressure roller; a duct which is formed in a long shape in a direction along an axis of the heat roller, is disposed in the vicinity of the fuser unit along the axis of the heat roller, and is exhausted by an exhaust fan which is provided on one end side in a long-side direction; an exhaust port which is opened to a first side wall of the fuser unit side of the duct and causes the fuser unit and the duct to communicate with each other; and a planar filter which is attached to an inner wall surface of the duct and in which the surface of the filter is an irregular surface on which ditches and convex portions extending in a direction inclined to the long-side direction of the duct are alternately disposed in the long-side direction of the duct.

Image forming apparatus

An image-forming apparatus comprising a fuser assembly including a heating roller and a pressure roller for fixing a non-fixed image on paper, a duct located in the vicinity of the fuser assembly in parallel to an axis line of the heating roller, an exhaust outlet located on a first side wall of the duct at the fuser assembly side, wherein the exhaust outlet is provided to connect the fuser assembly and the duct, and a plane filter detachably attached to an inside wall of the duct in parallel to the inside wall.
