Developing device having a control electrode.

摘要

Apparatus for developing an electrostatic latent image formed on a photoreceptor (1) with developer, includes a developing sleeve (81), a plate (85) disposed between the photoreceptor and the sleeve, an electrode member fixed to the plate member, and a bias member for forming the first oscillating electric field between the electrode member (85) and the sleeve (81) and the second oscillating electric field between the photoreceptor (1) and the sleeve (81). <IMAGE> <IMAGE>
