An image forming device includes an information storage part which stores sales package information and function package information. A function package information updating part increments, when activation of a sales package is performed, an activation component number of each of program components of the sales package in the function package information, and sets a flag of one of the program components to an activated state when the flag of one of the program components prior to the activation indicates a deactivated state. A starting information updating part registers a component identifier of one of the program components into starting information when the flag of one of the program components is changed from the deactivated state to the activated state by the activation.
