Abstract
An ink-jet image-forming method having the steps of: setting image areas, each having a predetermined range, in association with respective dots, and calculating a black dot area rate representing the density of dots formed in each image area. In the case when, among these dots, a group of high-density dots corresponding to image areas in which the black dot area rate is greater than a predetermined value are printed, slow-drying ink and quick-drying ink are used. In the case when dots having a black dot area rate smaller than the predetermined value are printed, the slow-drying ink is used. Thus, it is possible to shorten the ink drying time, and also to prevent degradation in the image quality.
