PROBLEM TO BE SOLVED: To provide an image processing unit that reduces moire and prevents a character from being thickened while warranting the density of a consecutive tone image such as a black solid part. SOLUTION: When an edge area detection means 6 detects an edge area, a density conversion processing section 3 selects a density conversion characteristic in which maximum output data take a comparatively lower value and when the edge area detection means 6 detects an edge area, the density conversion processing section 3 selects a density conversion characteristic in which maximum output data take a comparatively higher value. |
