ABSTRACT:
An image forming technique uses dots having at least two or more kinds of sizes are formed with respect to each of two kinds of coloring agents having different coloring concentrations, the optical density of the minimum dot of the coloring agent having a high coloring concentration is set to be smaller than the optical density of the maximum dot of the coloring agent having a low coloring concentration. It is possible to realize a gradient expression such that no pseudo outline due to the difference in dot concentration is generated even if there is a sudden density change.
