する現像装置のトナー検出機構。[Claims for Utility Model Registration] A toner storage tank containing non-magnetic monocomponent toner, a supply roller for supplying the toner within the toner storage tank, and a developing roller facing the supply roller. and a regulating member that is in pressure contact with the circumferential surface of the developing roller so that the toner supplied from the supply roller adheres to the surface of the developing roller in a uniform thickness, and the regulating member statically controls the toner conveyed by the developing roller. In a toner detection mechanism of a developing device that adheres to an electrostatic latent image on an electrostatic latent image carrier and develops it into a visible image, the toner detection mechanism has a detection portion such as a magnetic material at one end and rotates as the toner flows. A lever and a sensor for detecting a detected portion of the lever are provided in the toner storage tank so as to face each other, and the presence or absence of toner in the toner storage tank is detected by detecting the detected portion of the lever. The toner detection mechanism of the developing device.
