An object of the present invention is to suppress excessive charging of toner particles in a low-humidity environment, having a stable charging ability even in a low-humidity environment, a decrease in developer concentration due to environmental changes in temperature and humidity, fogging, and sleeve ghost. The present invention provides an electrophotographic developing method that suppresses deterioration in developability such as deterioration of image quality and has development stability. In an electrophotographic developing method in which development is performed by moving to an electrostatic latent image formed on an electrostatic latent image carrier, a substrate 2 and a resin coating layer 1 are provided on the surface, and the resin coating layer has sulfur atoms. And a developer carrier that contains a compound having a nitrogen atom, a sulfur atom content and a nitrogen atom content satisfying a specific relationship, and a toner particle containing a binder and a magnetic substance containing magnetic iron oxide The toner particles include b, and a developer in which the ratio of the content ratio of iron atoms to the content ratio of carbon atoms and the release ratio X of iron and iron compounds from the toner particles satisfy a specific relationship is used.
