ABSTRACT:
The ink jet recording apparatus includes an ink jet head that causes an electrostatic force to act on ink containing charged colored particles based on an image signal to eject an ink droplet on a recording medium, an ink supply unit that supplies the ink to the ink jet head, an ink collection unit that collects the ink not ejected from the ink jet head and a particle diameter distribution narrowing unit that narrows a particle diameter distribution of the charged colored particles contained in the ink. The narrowing unit includes an electrode cleaning unit that cleans an electrode for generating electrophoresis in the ink.
