According to the present invention, removal control of performing both first and second control in order is performed. The first control includes rotating a plurality of developer support members while a developer bias is applied to the developer support members so as to apply force to a reversely polarized particle of a toner regularly charged toward an image support member from a developer support member in a direction of moving a particle. The second control includes applying a development bias to the developer support members or rotating one developer support member at a faster peripheral velocity than the other developer support members with the development bias turned off, so as to apply force to the reversely polarized particle of the toner regularly charged toward the image support member from the developer support member. |
