Abstract

PURPOSE:To facilitate a complete filtration, the removal of clogging in a filter and a filter exchange, by providing an ink jet head with a filter composed of a magnetic powder. CONSTITUTION:For instance, a magnetic powder 16 is fed through an upper hopper 13 into an ink feed line 4, to form packed filters 6, 6 having a desired filtering property. An ink 5 is fed through the filters 6, 6 abd a porous filter 8 to an ink jet head 1, and injected from an orifice 2 in accordance with a signal from a pizeoelectric element 3. When clogging is generated in the filters 6, 6, a valve 9 is rotated so that the magnetic powder 16 is discharged through an opening 9a and reserved in a pan 11.
