Claims

[Claims for Utility Model Registration] 1. A photoconductor, and a photoconductor disposed adjacent to the photoconductor,
A developing housing that stores a two-component developer, a developing sleeve that is installed inside this housing and that rubs a magnetic brush against the photoreceptor to visualize an electrostatic image, and a stirring roller that is also installed inside the developing housing. and,
The developing housing includes a toner replenishing means for replenishing toner of the two-component developer, and the toner replenishing means stores at least a toner hopper having a substantially horizontal inner bottom surface and an opening in the inner bottom surface. A belt conveyor whose outer circumferential surface is made of a porous elastic material, a drive roller that is wound around the belt conveyor along the inner bottom surface of the toner hopper, and sends a substantially constant amount of toner to the developer housing through the opening of the toner hopper, and its driven roller. A developing device for a copying machine consisting of a roller. 2. A developing device for a copying machine according to claim 1, wherein the driving roller and its driven roller are wound so that the outer peripheral surface of the belt conveyor slides on the inner bottom surface of the toner hopper even before the opening of the toner hopper in the moving direction. Device. 3. The developing device for a copying machine according to claim 2, wherein the toner hopper is provided with a protrusion that sinks into the outer peripheral surface of the belt conveyor at the rear of the inner edge surface of the opening in the moving direction.
