1. An image forming apparatus capable of processing PDL data, comprising:
an analysis unit configured to analyze the PDL data;
a replacement unit configured to perform, in a case where a color represented by color values obtained by the analysis is a specific color, replacement processing to replace the specific color with another color;
a generation unit configured to generate, in a case where the replacement processing has been performed, a list for restoring the other color to the specific color,
a rasterizing unit configured to generate raster image data by performing rasterizing processing based on color values obtained by the analysis or color values of the other color, which have been replaced by the replacement processing; and
a storage unit configured to store the raster image data, wherein
the storage unit stores the raster image data in association with the list in a case where storage instructions are given by the PDL data.
