A developing means (4) develops a latent image with a developing agent. A supply means (200) supplies, to the developing means, a developing alternating current bias voltage with a waveform having a pulse period during which a rectangular wave is output and a blank period during which no rectangular wave is output. An input signal generation means (201) generates, as an input signal to be supplied to a primary side of a transforming means (T1) that forms the developing alternating current bias voltage, an input signal obtained by adding an additional pulse smaller in width than the rectangular wave in the pulse period at a timing to transit from the pulse period to the blank period. |
