Abstract
A toner discharging member is in contact with a developing sleeve at a position downstream to a developing region at which the developing sleeve (developer carrying member) confronts an electrostatic latent image carrier, extra toner returning to a toner supply region after the development is brought into contact with the discharging member and moves between the discharging member and the developing sleeve, a discharging bias voltage is applied to the toner discharging member, and the discharging bias voltage thus applied is controlled based on a toner charged state, an adhesion state of toner onto the electrostatic latent image carrier, a current flowing through a toner discharging member and others.
