摘要： A nozzle surface (13) is sealed by a cap member (44) in a state in which an ink solution is accumulated in a sealed hollow portion (45). After the nozzle surface (13) is sealed, piezoelectric vibrators (35) are driven by applying thereto a high-frequency drive signal of a frequency higher than a drive frequency for ejecting the ink solution toward recording paper, thereby causing cavitation in the ink solution. The firmly adhering thickened ink and solidified ink occurring in nozzle openings (29) are broken or exfoliated by bubbles caused by this cavitation. Subsequently, the suction operation is performed to remove the thickened ink and the solidified ink from the nozzle portions.

摘要： An ink jet recording method comprising the step of printing two solutions of a first solution and an ink composition is provided which, even in the case of printing on a recycled paper, can realize a good printed image, especially an image having no significant feathering and free from unevenness of printing and an image free from color bleeding. A first solution containing a polyvalent metal salt and/or a polyallylamine is used in combination with an ink composition containing an inorganic oxide colloid, and optionally an epoxy-containing compound. Specifically, the first solution is deposited onto a recording medium, and the ink composition is then deposited by ink jet printing to perform printing.
