An image-forming apparatus, comprising:
- a fuser assembly including a heating roller and a pressure roller for heating and pressurizing paper, on which a non-fixed image is applied and fixed;
- a duct located in the vicinity of the fuser assembly in parallel to an axis line of the heating roller, wherein a longitudinal direction of the duct is parallel to an axis line of the heating roller, and air in the duct is exhausted by an exhaust fan located at an end of the duct in the longitudinal direction;
- an exhaust outlet located on a first side wall of the duct at the fuser assembly side, the exhaust outlet being provided to connect the fuser assembly and the duct;
- and
- a plane filter attached to an inside wall of the duct;
- wherein a surface of the filter includes a concave-convex surface including a plurality of groove portions and a plurality of projecting portions, which extend orthogonally to the longitudinal direction of the duct, and the plurality of groove portions and the plurality of projecting portions are located respectively along the longitudinal direction of the duct.
An image-forming apparatus, comprising:
- a fuser assembly including a heating roller and a pressure roller for heating and pressurizing paper, on which a non-fixed image is applied and fixed;
- a fuser assembly enclosure surrounding the fuser assembly;
- a duct including a first side wall, which is a part of a wall section of the fuser assembly enclosure, wherein a longitudinal direction of the duct is parallel to an axis line of the heating roller and an air in the duct is exhausted by an exhaust fan located at an end of the duct in the longitudinal direction;
- an exhaust outlet located on the first side wall, the exhaust outlet being provided to connect the fuser assembly enclosure and the duct;
- and,
- a plane filter attached to an inside wall of the duct;
- wherein a surface of the filter includes a concave-convex surface including a plurality of groove portions and a plurality of projecting portions, which extend orthogonally to the longitudinal direction of the duct, and the plurality of groove portions and the plurality of projecting portions are located respectively along the longitudinal direction of the duct.
