Abstract
A predetermined pattern is printed on a recording sheet,for monitoring by using a recording head, and read by a reading device,so that abnormal recording elements are detected. Thus, a non-defective image is obtained in such a way that based on this detection result, image data to be supplied to the abnormal recording element is moved to image data of other recording elements to complement the recording. Despite the occurrence of abnormal recording elements, a desired non-defective image can be obtained.
