A developer container for storing the liquid developer; a developer carrying member for carrying the liquid developer; and a grooved developer supply member for feeding the liquid developer from the developer container to the developer carrying member. A developing section;
An image carrier to be developed by the developer carrier;
An intermediate transfer member onto which the developed image is transferred to the image carrier;
A non-image formation detection unit that detects when an image is not formed;
A developer supply member application bias controller for controlling a DC bias applied to the developer supply member;
A developer carrier application bias controller for controlling a bias applied to the developer carrier;
A developer supply member drive controller for controlling the drive of the developer supply member;
A developer carrier drive controller for controlling the driving of the developer carrier;
When the non-image formation detection unit detects a time when an image is not formed, a DC bias applied to the developer supply member by the developer supply member application bias control unit is controlled by a developer carrier application bias control. The developer supply member drive control unit drives and controls the developer supply member in a state where the portion is higher than the bias applied to the developer carrier, and the developer carrier drive control unit controls the developer carrier. A control unit for controlling the drive,
An image forming apparatus comprising:
