Abstract: PROBLEM TO BE SOLVED: To prevent toner from cohering in the opposing part between a blade 9 and a developing roller 8 by moving it in reciprocation, to stably form a uniform toner layer with sufficient electrification on the developing roller 8 for a long term, and further to prevent toner from being scattered outside a developing device, in the developing device wherein a contact part of the developing roller 8 of the blade 9 for limiting layer thickness is formed from an insulating material. SOLUTION: The above blade 9 is formed by laminating insulating layers 9b on a conductive layer 9a, and is attached to a casing 7 so that the insulating 9a comes into contact with the developing roller 8 on the edge or on the side. A blade voltage for forming an alternating electric field superposed with a DC component on the contact part between the insulating layer 9a and the developing roller 8 is applied to the above conductive layer 9a by a blade bias power source 12. This DC component is set so that the toner electrified with a prescribed polarity by a potential difference between the DC component and the above developing bias voltage is applied with the electrostatic force acting to the front side of the developing roller 8.
