Abstract
In an image forming apparatus, an image formation process is performed on image data in units of print jobs in a print mode of either one of a single-color print mode and a color print mode, the print mode is controlled to become the color print mode from the first page of the image data to a page of a designated page number, the print mode is controlled to become either one of the single-color print mode and the color print mode in a case where the designated page number is reached, and the designated page number is changed based on the number of the print jobs in a case where the image formation process reaches a designated number of times.

An image forming apparatus, comprising:
- an image formation process unit configured to perform an image formation process on image data in units of print jobs in a print mode of either one of a single-color print mode and a color print mode;
- a print mode control unit configured to control the print mode to become the color print mode from the first page of the image data to a page of a designated page number, and to control the print mode to become either one of the single-color print mode and the color print mode in a case where the designated page number is reached;
- and
- a change unit configured to change the designated page number based on the number of the print jobs.
