Claims

[Claims for Utility Model Registration] 1. An electrophotographic copying machine using a dry development visible image transfer method, comprising a developer removing means for collecting and removing developer remaining on the surface of a photoreceptor after the visible image has been transferred, and a photoreceptor. a developing device comprising a developing roller that visualizes an electrostatic latent image formed on the body, a developing container containing a developer, and a toner supply means that supplies toner to the container through a toner supply port; a toner re-supply port provided in the vicinity of the toner supply port of the developer container, and a developer conveying means for transporting the developer collected and removed by the developer removing means to the developer container via the toner re-supply port;
An electrophotographic copying machine comprising: 2. The electrophotographic copying machine according to claim 1, wherein the developing device includes an agitation device that moves the developer in the same direction as the axial direction of the developing roller.
