    Abstract: An image corresponding to a single sheet of recording paper is divided into three decomposed images(1,2,3) each having the substantially same expansion as that of the image, and one of the decomposed images is recorded on the recording paper while a drum is rotated and the recording head is continuously moved at a distance corresponding to a width of the recording head. Subsequently, other decomposed images are successively recorded on the recording paper. Thus, recording of the respective decomposed image is performed at a predetermined time interval kept between two continuous recordings. The foregoing time interval can be used as a time required for ink permeation into the recording medium.
