摘要：
The image forming apparatus comprises a resolution converting unit configured to convert a high-resolution image data into a low-resolution image data, an edge judgment unit configured to judge a shape of an edge in the high-resolution image data, and a density correcting unit configured to make a density correction in the low-resolution image data in accordance with the shape of the edge judged by the edge judgment unit.
