Abstract:
1. An image forming apparatus comprising: a transmitter for transmitting data comprising a pulse signal; a receiving portion for receiving the data comprising the pulse signal and transmitted from the transmitter; a data segmenting portion for segmenting the data comprising the pulse signal into predetermined segments; a fluctuations number counting portion for counting the number of pulse-signal fluctuations in the data segment segmented by the data segmenting portion; a determining portion for determining whether the number of pulse-signal fluctuations in the data segment counted by the fluctuations number counting portion exceeds a predetermined number or not; a transmission data controller which causes the transmitter to transmit the data comprising the pulse signal in an unchanged manner when the determining portion determines that the number of pulse-signal fluctuations in the data segment does not exceed the predetermined number, and when the determining portion determines that the number of pulse-signal fluctuations in the data segment exceeds the predetermined number, the transmission data controller converts the pulse signal and causes the transmitter to transmit the data with the converted pulse signal, the converted pulse signal is unchanged when the pulse signal fluctuates and is fluctuated when the pulse signal does not fluctuate; and a converting portion for converting the converted pulse signal received by the receiving portion to the original pulse signal.
