Abstract:
1. An image foaming device comprising: an image forming unit configured to form an image based on image data by using at least one of at least four colors of developer; a test image forming unit configured to control the image forming unit to form a test image based on test image data; a measuring unit configured to measure density of the test image; a color density correction data creating unit configured to create the color density correction data based on the measured density; a color order setting unit configured to set a color order; a performing unit configured to perform a color density correction data creating process for the at least four colors one by one in the color order to create color density correction data for the at least four colors, by controlling the test image forming unit, the measuring unit, and the color density correction data creating unit; a print image data acquiring unit configured so as to be capable of acquiring print image data while the performing unit is presently performing a color density correction data creating process for a current color of the at least four colors; a to-be-used color determination unit configured to determine, based on the print image data, a to-be-used color among the at least four colors, the to-be-used color being a color that should be used for forming a print image based on the print image data by the image forming unit; a first determining unit configured to determine whether or not the performing unit has already performed the color density correction data creating process for the to-be-used color; and a print image forming unit configured to control the image forming unit to form the print image based on the print image data by using the color density correction data corresponding to the to-be-used color, when the print image data acquiring unit acquires the print image data before the performing unit has performed the color density correction data creating process for all of the at least four colors after the performing unit started performing the color density correction data creating process and when the first determining unit determines that the performing unit has already performed the color density correction data creating process for the to-be-used color; wherein the performing unit continues to perform the color density correction data creating process to completion to create the color density correction data for one of the at least four colors before the print image forming unit controls the image forming unit to form the print image if the performing unit is performing the color density correction data creating process for the one of the at least four colors when the print image data acquiring unit acquires the print image data and the first determining unit determines that the performing unit has already performed the color density correction data creating process for the to-be-used color, and wherein the performing unit does not start performing the color density correction data creating process to create the color density correction data for one of the at least four colors and the print image forming unit controls the image forming unit to start forming the print image if the performing unit has not yet started to perform the color density correction data creating process for the one of the at least four colors when the print image data acquiring unit acquires the print image data and the first determining unit determines that the performing unit has already performed the color density correction data creating process for the to-be-used color.
