Abstract
The present image forming apparatus, upon accepting, in accordance with a user input, an instruction for execution of processing for adjusting an image forming condition, forms a predetermined test pattern on a sheet, and detects the density of the predetermined test pattern. Furthermore, the image forming apparatus obtains an area ratio of halftone dots in a highlight region of a formed image from the detected density, and, based on the area ratio of halftone dots, decides a smallest dot size for a screen that represents a halftone of the highlight region by a dither pattern.
