Abstract
Upon receiving a request to control developing bias voltage, first and second square-wave signal output units output first and second square-wave signals, respectively. When a rising edge of the first square-wave signal coincides with a rising edge of the second square-wave signal, the rising edge of the second square-wave signal is advanced with respect to the rising edge of the first square-wave signal. When a falling edge of the first square-wave signal coincides with a falling edge of the second square-wave signal, the falling edge of the second square-wave signal is delayed with respect to the falling edge of the first square-wave signal. Subsequently, a voltage-controlling square-wave signal for controlling developing bias voltage is generated based on the first and second square-wave signals.
