Abstract: An image forming apparatus includes a longitudinally conveying motor, a main-body-side control board, and a sensor. In the longitudinally conveying motor, an encoder generates an encoder signal having a frequency corresponding to the number of rotations of the longitudinally conveying motor, and a sensor signal superimposing unit receives an input of a logical state of the sensor. The sensor signal superimposing unit superimposes the logical state of the sensor on the encoder signal by modulating a duty ratio of the encoder signal based on the logical state of the sensor, and outputs a post-superimposition encoder signal. In the main-body-side control board, a sensor signal separating unit obtains the logical state of the sensor by demodulating the input encoder signal.
