Abstract:
An ink jet recording apparatus for ejecting a recording liquid from an ejection port at the tip of a liquid passage in a nozzle, comprising:a recording head temperature detection means for detecting the temperature of a recording head; an image data thinning means for performing a thinning operation of print image data so that print image data corresponding to a first raster is thinned at a predetermined rate and print image data corresponding to a second raster is not thinned, when the temperature of the recording head detected by said recording head temperature detection means exceeds a predetermined temperature; and a recording head drive control means for controlling driving pulses for driving the recording head, wherein said recording head drive control means controls driving pulses so that driving pulses applied in recording said first raster and driving pulses applied in recording said second raster differ from each other.
