Claim:
An image forming device comprising: an image forming section that forms an image in accordance with predetermined conditions; a storage section that stores a target darkness of a standard image; a measurement section that measures a physical quantity for specifying the darkness of the image formed by the image forming section; a user calibration section that causes the image forming section to form the standard image in response to an instruction input by a user, causes the measurement section to measure the physical quantity when the standard image is formed, and if there is a discrepancy between the darkness of the standard image specified by the measurement of the physical quantity and the target darkness stored in the storage section, adjusts the image formation conditions to eliminate the discrepancy; a manual darkness adjustment section that changes the image formation conditions to content specified by the user and is reflected in forming images other than the standard image; and a control section that has a first operating mode in which, during an operation by the user, when the user calibration section causes the image forming section to form the standard image, causes the image forming section to follow image formation conditions that do not reflect the content changed by the manual darkness adjustment section, wherein the standard image is used for adjusting forming conditions of the image forming apparatus, wherein the manual darkness adjustment section is not reflected in results with respect to generation of the standard image, even if the manual darkness adjustment section is initiated before the user calibration section, and the manual darkness adjustment section is performed before the user calibration section and is reflected in the results with respect to generation of the image forming conditions.
