の電子写真現像装置。[Claims for Utility Model Registration] 1. A developing roll consisting of a cylindrical sleeve made of a non-magnetic material, a permanent magnet roll rotatably installed inside the sleeve and having a plurality of magnetic poles extending in the axial direction; a hopper arranged to surround at least a portion of the developing roll for storing developer; and a developer regulating member for regulating the layer thickness of the magnetic developer carried and conveyed on the sleeve of the developing roll. In the electrophotographic developing device, a thin plate having a predetermined inclination with respect to the flow direction of the magnetic developer is provided on the inner wall of the developing device, which serves as a path for the magnetic developer regulated by the developer regulating member. An electrophotographic developing device characterized by: 2. A utility model registration request characterized in that the thin plate is arranged at a position apart from the regulating part of the developer regulating material by a certain distance, and the position is higher than the developer remaining amount detection device. The electrophotographic developing device according to scope 1. 3. The thin plate is partially disposed with respect to the axial direction of the developing roll, and is provided with an inclination toward the side where the thin plate is not provided, and at a position where there is no thin plate,
An electrophotographic developing device according to claim 1, further comprising a sensor for detecting the remaining amount of magnetic developer.
