PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing image- flowing and filming by maintaining the effect of satisfactorily grinding a photoreceptor drum by a cleaning roller, even under conditions such as a job setting condition, the working hysteresis of an image forming device and the environmental condition, etc., that are likely to cause image-flowing or filming. SOLUTION: The image forming device is provided with a cleaning means equipped with a rotating body for cleaning, a voltage applying means for applying a bias voltage whose polarity is opposite to that of toner to the rotating body, a detecting means for detecting the working information on the image forming device, and a bias voltage control means for controlling the bias voltage of the voltage applying means in accordance with the detection result of the working information. |
