方法として注目されている。(Prior Art) Inkjet recording methods include various ink (recording liquid) ejection methods, such as an electrostatic suction method, a method that applies mechanical vibration or displacement to the ink using a piezoelectric element, and a method that heats the ink to foam it. Recording is performed by generating and flying small droplets of ink using the pressure, and attaching some or all of them to a recording material such as paper.
It is attracting attention as a recording method that generates little noise and allows for high-speed printing and multicolor printing.

詰まりの原因となる。(4) When inkjet recording is performed on a recording material, the coating layer peels off due to the mechanical friction between the recording material and the paper feeding portion of the recording device, which is called powder falling, which contaminates the recording device. In particular, if the fallen ink receiving layer adheres to the head of an inkjet recording device, it may cause clogging of the nozzles of the head.
