Abstract
An air flow is generated in a space adjacent to the toner control member 3, when an image is not being formed, and also a cleaning electric field for moving the toner away from the toner control member 3 is generated in the same space. For instance, a slit 2a is formed in an outer peripheral section of a cylindrical and rotatable counter electrode member 2, and an air flow generating source 10 such as a fan is connected to the counter electrode member 2. A convex cleaning electrode 11 is formed around the slit 2a of the counter electrode member 2, and a voltage for forming a cleaning electric field is applied from the power supply source for cleaning 8 to this cleaning electrode 11.
