Abstract
Removal control performing both first and second control in series is performed. The first control involves rotating the plurality of developer bearing members in a state in which the developing bias is applied to the plurality of developer bearing members so that force acting on opposite-polarity particles from a normally charged toner in the direction of moving the particles from the developer bearing member toward the image bearing member. The second control involves rotating one developer bearing member at a faster circumferential velocity than the other developer bearing member in a state in which the developing bias is applied to the plurality of developer bearing members or the developing bias is turned off so that the force acting on the opposite-polarity particles from the normally charged toner in the direction of moving the particles from the developer bearing member toward the image bearing member.
