An exhaust emission control system for an internal combustion engine is provided which includes a NOx storage / reduction catalyst disposed in an exhaust passage of the engine, and a NOx sensor positioned in the exhaust passage downstream of the catalyst. A controller of the system performs a rich-spike operation to temporarily operate the engine at a rich air / fuel ratio each time a NOx storage state of the catalyst satisfies a predetermined rich-spike condition during a lean-burn operation. When the degree of degradation of the catalyst is determined by comparing the output of the NOx sensor with a predetermined evaluation value, the rich-spike condition is changed so that the amount of NOx stored in the catalyst at the time of a start of the rich-spike operation during a degradation determination period is made larger than that reached during a period other than the determination period.

The image quality deterioration due to the collection of dots of low-lightness by the preliminary ejection is prevented, in the case of performing the ink ejection for preliminary ejection during the printing onto printing paper. More specifically, the preliminary ejection pattern is set as a pattern in which the distance between a cyan dot of relatively low-lightness and a magenta dot is longer than a distance between a yellow dot of relatively high-lightness and a cyan dot nearest the yellow dot among low-lightness colors. Closely forming dots of low-lightness that would be perceived as a group of collected dots can be prevented, thereby performing printing that will not deteriorate the printing quality due to the paper preliminary ejection.
