PROBLEM TO BE SOLVED: To prevent deterioration of an image due to clogging of a filter. SOLUTION: A filter 25 is disposed so as to divide a region in the filter section 12a of an ink reservoir 12 to be two parts. A rotator 30 of a magnetic material is provided to a portion in the vicinity of the surface of the filter 25. A stirrer 31 having a magnet 32 in its inner section is provided to a position where a magnetic force can work between the stirrer 31 and the rotator 30. When the magnet 32 in the stirrer 31 is rotated, the rotator 30 is rotated along with the rotation of the magnet 32. The flow of ink 2 at a portion in the vicinity of the surface of the filter 25 becomes turbulence, and then a residue material of ink formed on the surface of the filter 25 can be removed from the surface of the filter 25. |
