装置。[Claims for Utility Model Registration] 1. A hopper opening formed by a regulating member that comes into contact with the surface of the developing roll to form a developer layer thereon and a bottom wall of the hopper containing the developing roll; In a one-component developing device in which a one-component developer is transferred from the developing roll onto an electrostatic latent image holder through a hopper opening to visualize an electrostatic latent image, an elastic foam fixed to the bottom wall of the hopper is used. An insulating film is interposed between the body and the developing roll, the elastic foam and the developing roll are brought into surface contact via the insulating film, and the elastic foam and the insulating film are bonded together. A one-component developing device characterized by: 2. The one-component developing device according to claim 1, wherein the charging polarity of the insulating film is the same as the charging polarity of the developer. 3. The one-component developing device according to claim 1, wherein the cell size of the elastic foam is smaller than the minimum particle size or average particle size of the developer.
