ものである。As shown in FIG. 1, the ink side recording apparatus ejects ink droplets 2 from an inkjet head 1, applies charges to the ink droplets 2 by a charging electrode 3, and transfers them to a deflection electrode 4, which converts them into signals. Based on this, the image is deflected and printed on the surface of the recording paper 5. In this case, when the ink droplet 2 collides with the recording paper 5, an ink mist 6 is generated around the recording paper 5, and this ink mist 6 adheres to the surface of the recording paper 5, degrading printing quality. Therefore, an ink absorbing portion 7 is disposed between the deflection electrode 4 and the recording paper 5. This ink absorbing member 7 and LTE, 5VS303,
A porous metal obtained by sintering a metal such as SVS 304° austenitic metal is used. Reference numeral 8 in the figure denotes a large-capacity ink absorbing member, which is connected to the ink absorbing member 7 and stores all the ink absorbed by the ink absorbing member 7.

。The ink absorbing member 7 is composed of a sintered body made of porous metal as described above, but since this sintered body is manufactured using a mold, it has a flat surface as shown in FIG. Part 9
There is. Therefore, if the ink mist 6 generated by colliding with the recording paper 5 hits this flat portion 9, it will bounce back and conversely stain the surface of the recording paper 5, resulting in an insufficient absorption effect.

By forming f and r, the splashing phenomenon of the ink mist from the previous ink is eliminated, and the ink absorption capacity is dramatically increased. (Thus, inkgeno) The atmosphere around the head has been significantly improved, and the recording paper is free from stains.
A clear printed image can be obtained.
