像装置。[Scope of Claim for Utility Model Registration] 1. A developing device disposed opposite to the image carrier to develop an electrostatic latent image formed on the image carrier with a developer, the developer being inside the image carrier. a housing accommodated in the housing; a level sensor provided in the housing to detect the level of the developer contained in the housing; and a developer provided in the housing at a position below the placement position of the level sensor. A developing device comprising: a discharge port; and an opening/closing member disposed to be able to open and close the developer discharge port and opened and closed based on the detection result of the level sensor. 2. The opening/closing member opens the developer discharge port when the level sensor detects developer at a predetermined level or higher, and closes the developer discharge port when the level sensor detects developer at a predetermined level. Claim No. 1 for Utility Model Registration
Developing device described in Section 1. 3. The developing device according to claim 2, wherein the opening/closing operation means of the opening/closing member is a solenoid.
