Abstract
An image forming apparatus which makes it possible to perform an image forming operation even during update of a control program. The image forming apparatus is provided with distributed module controllers each including a sub CPU and a flash ROM storing a control program for controlling the sub CPU. The main CPU of the image forming apparatus updates the control programs stored in the respective flash ROMs. The main CPU displays a screen that enables selection of functions to be used in an image forming job executed by the image forming apparatus. During execution of update of a control program targeted for update, out of the selectable functions, the main CPU disables a function which uses a sub CPU associated with the control program.
