Abstract:
An AC measuring circuit measures a magnitude of an alternating current flowing through a bias applying circuit synchronized with a cycle of an AC voltage in a developing bias voltage. A control unit changes a level of the AC voltage in the developing bias voltage, and executes a developing bias adjustment process for setting a level of the AC voltage based on the level of the AC voltage when the leakage current detecting circuit detects the direct current. The control unit, when a measurement by the AC measuring circuit during execution of a developing process exceeds a predetermined allowable value, executes a warning process to prompt execution of the developing bias adjustment process, or the control unit executes the developing bias adjustment process to update the level of the AC voltage.

Claim (Index 3):
The image forming apparatus according to  claim 1 , wherein\n multiple pieces of correspondence information are preliminarily set, each piece indicating a corresponding relationship between the level of the AC voltage and a control value, and each piece corresponding to a different magnitude of the AC voltage, and the control device, based on the multiple pieces of the correspondence information and the measurement result of the AC measuring circuit, derives the control value corresponding to the developing bias AC level and outputs the derived control value to the bias applying circuit.
