Abstract
In a color image recording apparatus provided with plural print heads and a conveyor, each print head includes a plurality of recording elements aligned along at least a single line in a primary scanning direction and the plural print heads are arranged in parallel to each other in the primary scanning direction so that plural component images of the color image are formed parallel respectively by the plural print heads. A reference component image forming device controls the plural pieces of print heads so as to form and superimpose plural reference component images based on the reference component image data and timing setting values. A timing correcting unit analyzes positional deviations in the secondary scanning direction among the plural superimposed reference component images and corrects the timing setting values on the basis of the positional deviations in the secondary scanning direction.
