Claims

[Claims for Utility Model Registration] 1. A roller for forming a magnetic brush is provided inside to develop the electrostatic latent image on the photoreceptor into toner, and an opening is formed in a portion facing the photoreceptor, In the developing device in which a portion of the roller protrudes from the opening, a ductor blade that is bent from the outer bottom surface of the developing device main body along the opening is bent about the protrusion formed on the outer bottom surface as a fulcrum. A developing device for an electrostatic recording machine, characterized in that the developing device is mounted so that its free edge can swing in a state parallel to the rotational axis of the roller. 2 A spring is attached to one side of the protrusion to bias the free end edge of the doctor blade in a direction toward the outer circumferential side of the roller, and a spring is attached to the other side of the protrusion to force the free edge of the doctor blade toward the outer circumferential side of the roller. The developing device for an electrostatic recording machine according to claim 1, which is equipped with an adjustment screw that separates the free edge from the outer circumference of the roller. 3 A spring is attached to one side of the protrusion to bias the free end edge of the doctor blade in a direction to separate it from the outer circumferential side of the roller, and a spring is attached to the other side of the protrusion to bias the free edge of the doctor blade away from the outer circumferential side of the roller. The developing device for an electrostatic recording machine according to claim 1, which is equipped with an adjusting screw that brings the edge closer to the outer circumferential side of the roller.
