Abstract
A latent electrostatic image developing device. A developer agitating/conveying mechanism is disposed in a development housing and has an agitating/conveying member for conveying a developer, while agitating it, along a developer application. A toner concentration detector is disposed in the bottom wall of the development housing to oppose the agitating/conveying member. The upper surface and the side surface of a detector portion of the toner concentration detector are connected by an arcuate surface or a chamfered surface. The toner concentration detector is fitted into an opening formed in the bottom wall of the development housing, and the upper surface of the detector portion protrudes from the inner surface of the bottom wall of the development housing by an amount nearly corresponding to the radius of the arcuate surface or the height of the chamfer of the chamfered surface.
