Claims

[Scope of utility model registration request]

A developing roller that electrostatically attracts toner to an electrostatic latent image formed on the surface of a photoconductor, a fur brush that has bristles that supply toner to the developing roller, and a fur brush that is disposed within a developing device body that accommodates toner. In a developing device equipped with a dusting member that comes into contact with the bristles of the fur brush and brushes off toner that has entered the bristles, the dusting member is provided with a predetermined width on the side of the dusting member opposite to the bristles of the fur brush. The convex portions that come into contact with the hair body and the concave portions that are spaced apart from the hair body by a predetermined width are arranged alternately, and
A developing device comprising a reciprocating slide mechanism for reciprocating a dusting member in parallel with the axial direction of the fur brush so that the convex portion sequentially hits the entire length of the bristles as the fur brush rotates.
