In the image formation apparatus according to the present invention, a plurality of detection sections outputs binary signals to a detection identification control section, and an image formation control section for control of periphery of the engine of the apparatus outputs a detection section identifying signal and a detection section period signal to the detection identification control section. Also, the detection identification control section outputs a detection result of the detection sections as detection data to a control board. A plurality of driver sections are connected to a driver identification control section via a data line through which driving signals for driving a section to be driven are transmitted. Accordingly, the present invention provides a versatile image formation apparatus with a reduced number of output lines which can deal with a change of image formation system without increasing the number of signal lines.
