Image forming apparatus capable of backing up contents of settings for job

An image forming apparatus includes: a controller that allows a display device to display a settings screen for setting of a function by a user and executes a job based on a user setting made through the settings screen; and a backup device that backs up as backup data the user setting on a storage device each time the user setting is made. When execution of the job based on the user setting is completed, the controller deletes the user setting from the storage device. When, in newly displaying a settings screen on the display device for another job, the user setting for a function configurable on the settings screen is saved on the storage device, the controller determines the content of the user setting as a content of a setting for the job and allows the display device to display the settings screen showing the content of the setting.
