Image forming apparatus, imgae forming method, and program

An image forming method of an image forming apparatus including an attribute-value-information holding unit that holds an attribute-value table showing correspondence between a type of gradation processing and a fixing-temperature control attribute value, the image forming method comprising:

• determining a type of gradation processing and a corresponding fixing-temperature control attribute value on the basis of contents of a print instruction and the attribute-value table;
• performing gradation processing in accordance with the type of gradation processing determined at the determining;
• and
• controlling fixing temperature in formation of a print image according to the fixing-temperature control attribute value determined at the determining.

A computer program product comprising a computer readable medium having computer readable program instructions that, when executed in a computer including an attribute-value-information holding unit that holds an attribute-value table showing correspondence between a type of gradation processing and a fixing-temperature control attribute value, cause the computer to execute:

• determining a type of gradation processing and a corresponding fixing-temperature control attribute value on the basis of contents of a print instruction and the attribute-value table;
• performing gradation processing in accordance with the type of gradation processing determined at the determining;
• and
• controlling fixing temperature in formation of a print image according to the fixing-temperature control attribute value determined at the determining.
