PROBLEM TO BE SOLVED: To reduce a step-like step of an outline particularly for a character subjected to a halftone process for an image forming apparatus by an ink jet recording method, to realize high-speed recording and to improve image quality. It can be so. Font data that has not been subjected to halftone processing is expanded into bitmap data by printer driver software. Bitmap data indicates the dots forming the font. Pattern matching is performed on each bit for each bit of bitmap data as font data. Thus, a droplet is formed at the changing point. In this way, in the halftone processed character, when the halftone processing is not performed, the dot forming the outline is detected and the jaggy correction method is selected, or the jaggy correction method is selected according to the inclination of the hatched portion. select.
