<P>PROBLEM TO BE SOLVED: To prevent deterioration of an image quality caused by disagreement of a state of an image forming apparatus with a gamma curve used in gamma conversion processing. <P>SOLUTION: Image data transmitted from a printing controller 2 is subjected to gamma conversion processing on the basis of the gamma curve. The image data subjected to gamma conversion processing is stored in an image memory 13. In the image forming apparatus 1 which carries out image formation on the basis of the image data stored in the image memory 13, when conditions for executing correction of the gamma curve while a job is interrupted because of an error are satisfied, correction of the gamma curve is executed after the error is released. Thereafter, the image data stored in the image memory 13 is deleted, and the printing controller 2 is made to transmit the image data again. <P>COPYRIGHT: (C)2008,JPO&INPIT |
