Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dust removing filter which is installed inside electronic equipment such as copying machine, printer, multi-functional OA machine or POD printer, for the purpose of capturing dust e.g. toner, included in exhaust air from the equipment, and exhibits an ability to capture a well large amount of dust. SOLUTION: This dust removing filter is made up of a thermal bond nonwoven fabric obtained by mixing at least a polyolefin-based heat-adhesion fiber and a polyester-based fiber. In addition, the constituent weight ratio of the polyolefin-based heat-adhesion fiber and the polyester-based fiber of the thermal bond nonwoven fabric, is 99:1 to 60:40. The packing density of the thermal bond nonwoven fabric is not more than 0.07 g/cm3. COPYRIGHT: (C)2011,JPO&INPIT
