Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: a fuser unit extending in a longitudinal direction and including a heat roller and a pressure roller, which heats and pressurizes a sheet on which an unfused toner image is carried and fuses the unfused toner image on the sheet; a duct provided adjacent to the fuser unit to form an air flow along an air-flowing direction in parallel with the longitudinal direction of the fuser unit; an exhaust fan located on an axia…
