IMAGE FORMING APPARATUS |
摘要 |
An image forming apparatus has an image carrier, a charger, a developing device, a voltage application unit, and a controller. The developing device includes a developing roller. The voltage application unit applies a voltage to the developing roller and to the charger. The controller controls the voltage application unit. The controller controls the voltage application unit such that a developing bias having an AC voltage superposed on a DC voltage is applied to the developing roller and a charging bias including at least a DC voltage and having superposed thereon a compensation AC voltage with an opposite phase to an AC voltage induced in the charger by the developing bias is applied to the charger. |

1. An image forming apparatus, comprising:
an image carrier on which an electrostatic latent image is formed; a charger that electrostatically charges the image carrier; a developing device including a developing roller that is arranged opposite the image carrier and that supplies toner to the image carrier, the developing device storing developer containing toner and carrier; a voltage application unit that applies a voltage to the developing roller and to the charger; and a controller that controls the voltage application unit, wherein the controller controls the voltage application unit such that
a developing bias having an AC voltage superposed on a DC voltage is applied to the developing roller anda charging bias including at least a DC voltage and having superposed thereon a compensation AC voltage with an opposite phase to an AC voltage induced in the charger by the developing bias is applied to the charger. |
