PROBLEM TO BE SOLVED: To obtain an ink jet printer which can form a good image without requiring any intricate interpolation processing, e.g. alteration of mask pattern or the number of pass, even when a nonejection nozzle is detected. SOLUTION: The ink jet recorder comprises means for detecting a nozzle 408X in nonejection state among a plurality of nozzles 408, means for setting an optimal ejection quantity of a nozzle 408Y1 adjacent to a nonejection nozzle detected by the nonejection nozzle detecting means, and means for controlling ejection of a nozzle adjacent to the nonejection nozzle 408X based on a set value set by the ejection quantity setting means. |
