The image forming apparatus holds related restriction information associated with function restriction information for restricting the use of a function provided within the network. With the related restriction information, when the image forming apparatus receives a job that executes a reading function and a transmission function, it displays, for a transmission source user, a settings screen for setting job operation settings in which restrictions held in the function restriction information and the related restriction information have been reflected. Furthermore, the image forming apparatus generates and transmits a send file in which the restrictions imposed on the transmission destination user have been reflected by using the job operation settings set via the settings screen, the function restriction information and the related restriction information.
