を特徴とする静電潜像現像装置。 a rotationally driven developing roller which is provided facing the surface of the photoreceptor carrying the electrostatic latent image, has a cylindrical outer peripheral surface, and has a magnetic field generating member inside;
In an electrostatic latent image developing device, the electrostatic latent image developing device includes a spike-cutting member that is provided close to the outer circumferential surface of the developing roller and limits the spike height of the magnetic developer formed on the surface of the development roller. A mesh member is provided on the upstream side in the rotational direction of the developing roller, one end of which extends near the outer circumferential surface of the developing roller to prevent the mass of magnetic developer from being transferred to the ear cutting member. and a means for stretching a steel wire between the net-like member and the developing roller and at a portion further upstream of the net-like member and close to the outer peripheral surface of the developing roller, and vibrating the steel wire. An electrostatic latent image developing device comprising:
