Abstract: When rotation speed of second rotator is greater than or equal to a threshold previously determined, first control portion causes first generation portion to generate a first potential difference that enables toner in a predetermined amount to be transferred from first rotator to second rotator, and causes second generation portion to generate a second potential difference that enables the toner in the predetermined amount to be transferred from second rotator to a electrostatic latent image. When the rotation speed is less than the threshold, second control portion causes first generation portion to generate a third potential difference that enables the toner in an amount exceeding the predetermined amount to be transferred from first rotator to second rotator, and causes second generation portion to generate a fourth potential difference that enables the toner in the predetermined amount to be transferred from second rotator to the electrostatic latent image.

Abstract: An image forming apparatus includes an image carrier, a developing device, a bias applying unit, a leakage detecting unit, a bias control unit and a leakage detection control unit. The developing device includes a magnetic roller and a developing roller. The magnetic roller carries a developer layer by being rotated. The developing roller receives the toner from the developer layer and supplies the toner to the image carrier. The leakage detection control unit performs a leakage detecting operation of detecting a value of an inter-peak voltage, at which the leakage occurred. The leakage detection control unit simultaneously starts the leakage detecting operation for a plurality of developing devices and performs the leakage detecting operations of the developing devices in which leakage simultaneously occurred while switching the leakage detecting operations one by one if the leakage simultaneously occurs in a plurality of developing devices at an inter-peak voltage.
