Image forming device having function redundant system



PURPOSE: To provide an image forming device with the function which can be substituted for the specified function of the device by incorporating a function redundant system in the device. CONSTITUTION: In the case that the specified functional part of the device (image forming part 1) is not operated, the device is operated according to previously fixed combination so that the potential function of a remaining functional part is substituted for the original function of the specified functional part. The combination is previously calculated based on an FBS diagram (diagram consisting of function, behavior and state), stored in a memory, and selected by a ROM selection part 24.
