Image forming apparatus, control method for the same, and storage medium storing program therein

A control method for controlling an image forming apparatus that controls fixing of developer to a printing medium by controlling a temperature of a heating member of a fixing device, comprising:

• measuring an actual temperature of the heating member;
• controlling the temperature of the heating member;
• obtaining, based on image data that includes a plurality of pages, an application amount of the developer on a printing medium on which a page that is to be processed has been formed;
• obtaining, based on the image data, a coverage ratio of the developer on a printing medium on which a predetermined page has been formed;
• obtaining setting temperatures of the heating member that respectively correspond to the application amount and the coverage ratio;
• and
• controlling the temperature of the heating member based on the actual temperature that has been measured and the setting temperatures of the heating member that have been obtained, thereby performing control to subject the printing medium on which the page that is to be processed has been formed to fixing.

A non-transitory computer-readable storage medium that stores therein a program that causes a computer to:

• measure an actual temperature of a heating member of a fixing device;
• control a temperature of the heating member;
• obtain, based on image data that includes a plurality of pages, an application amount of a developer on a printing medium on which a page that is to be processed has been formed;
• obtain, based on the image data that includes the plurality of pages, a coverage ratio of the developer on a printing medium on which a predetermined page has been formed;
• obtain setting temperatures of the heating member that respectively correspond to the application amount and the coverage ratio;
• and
• control the temperature of the heating member based on the actual temperature that has been measured and the setting temperatures of the heating member that have been obtained, thereby performing control to subject the printing medium on which the page that is to be processed has been formed to fixing.
