<P>PROBLEM TO BE SOLVED: To provide a toner collection filter which has the function of sufficiently collecting toner and can be incinerated, and to provide a toner container which uses the filter. <P>SOLUTION: A laminated body 4 is formed by sandwiching a porous film 1 between air-permeable support members 2 and 3. As the porous film 1 and support members 2 and 3, nonwoven fabric made of fiber obtained from a fluorine non-containing material is used. The porous film 1 is formed so that capturing efficiency of particles becomes 60% or more when the particles of 1μm to 5μm diameter are passed through at a flow rate of 5.3cm/sec. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
