An image forming apparatus including at least a copying function, includes an engine board (100), an image reading unit (111) that reads an image of an original document to obtain image data and transfers the image data to the engine board (100), an image forming unit (112, 115) that receives the image data from the engine board (100) and forms the image on a transfer sheet based on the image data, a controller board (201) detachably connected to the engine board (100) to add at least one application function (APL 1) to the copying function of the image forming apparatus, an operation unit (110) that receives an operational instruction input by an operator of the image forming apparatus and displays information of the at least copying function of the image forming apparatus, and a parallel bus (120) that connects the controller board (201) to the engine board (100) and notifies the engine board (100) that the controller board (201) is connected to the engine board (100) when the controller board (201) is connected to the engine board (100). When the controller board (201) is connected to the engine board (100), the operation unit (110) displays the information of the copying function and the at least one application function, and when the controller board (201) is detached from the engine board (100), the operation unit (110) displays the information of the copying function, and each of display layouts of the operation unit (110) for the copying function is substantially identical between when the controller board (201) is connected to the engine board (100) and when the controller board (201) is detached from the engine board (100). <IMAGE> |
