The present invention relates to an image formation device, a display screen switching method, and a program. Excellent operability with user friendliness is realized by appropriately controlling switching of a display screen without increasing a burden on an operating system. In order to accomplish this, an image formation device 1 for example includes: a panel manager 33 for controlling switching of a display screen to be displayed on a display unit 5; a system controller 32 for controlling a hardware section; and an application section 39 for executing a specific function by putting the hardware section into operation through the system controller 32, and for creating a display screen relating to the specific function. When the system controller 32 detects the occurrence of an event with the display screen created in the application section 39 being displayed on the display unit 5, the panel manager 33 requests the application section 39 to determine whether or not switching of a display screen should be made, and controls switching of a display screen to be displayed on the display unit 5 based on a result of the determination made by the application section 39.
