<p>An image processing device for processing image data indicative of an image to be printed by a print execution section, the print execution section having a print head that is reciprocated in a main scanning direction and that is capable of printing a partial image in a unit printing area for each main scan. The image processing device includes: a process section; a generation section; and a supply section. The process section is configured to execute an image process on image data so as to generate processed image data. The generation section is configured to execute a halftone process on the processed image data so as to generate print data. The supply section is configured to supply the print data to the print execution section. The process section includes: an index value determination section; and an adjustment section. The index value determination section is configured to determine an index value for each of a plurality of target pixels included in edge image data, the index value for each target pixel being related to density of the target pixel, wherein the edge image data corresponds to an edge portion of a unit printing area and is part of partial image data within the image data, and the partial image data corresponds to the unit printing area. The adjustment section is configured not to adjust a pixel value of the target pixel in a first case where the density of the target pixel is determined to be relatively low based on the index value of the target pixel, and configured to adjust the pixel value of the target pixel so as to reduce the density of the target pixel in a second case where the density of the target pixel is determined to be relatively high based on the index value of the target pixel.
