A method for forming a recording position adjusting pattern that is capable of correcting a recording position correctly, a method for adjusting the image recording position, and an image recording apparatus are provided. Corrected K color parallel bars are grouped into blocks each of which includes a certain number of bars and plural blocks are printed in block (180, 188), and the color parallel bars are printed between the K color parallel bars with tilt magnitude that is different for every block (182, 190). The optical detection unit detects the block having the highest density among the printed parallel bars (184, 192), the tilt magnitude of the detected block is set as the tilt magnitude of the color to thereby correct the tilt of the color (186, 194). The tilt of each color is corrected in the same manner.
