Operating section for an image forming apparatus
 In an image forming apparatus, an operating section accessible for entering various information and commands is implemented as a plurality of key units. The key units are each removably connected to the body of the operating section via cooperative connectors. When any one of the key units is damaged or or the life thereof expires, only the defective unit is replaced while the other units are continuously used.
