1. An image processing method to record images on a recording medium using a recording head that ejects ink, the image processing method comprising:
generating N-value (N is an integer of 3 or more) text data and M-value (M is an integer of 3 or more) image data on the basis of input data; generating text record data of L values (L is an integer of 2 or more that is less than N) representing the ejection or absence of ejection of ink by quantizing the N-value text data; and generating image record data of K values (K is an integer of 2 or more that is less than M) representing the ejection or absence of ejection of ink by quantizing the M-value image data; wherein the text record data and the image record data are generated so that the image record data indicates no ejection of ink for pixels corresponding to pixels for which the text record data indicates an ejection of ink.
