Abstract
An image forming device includes an inkjet head unit, a count acquiring section, a determining section, and a head controlling section. The inkjet head unit includes an element. The count acquiring section acquires, based on job data, an element operation count of the element. The determining section determines whether the element operation count is equal to or greater than a warning threshold count that is smaller by a predetermined count than a life threshold count corresponding to a life end point of the element. The head controlling section controls, when the element operation count is equal to or greater than the warning threshold count, the inkjet head unit to form an image by suppressing the element operation count.
