Abstract
A developing method in an electrophotographic apparatus in which an image on an electrophotographic film brought into a developing section is developed by a developer supplied to the developing section. During the development, a seal gas of a pressure higher than the pressure in the developing section is supplied to a seal section around the developing section so that the seal gas is forced to flow into the developing chamber to stir the developer in the developing section, thus eliminating any degradation of the quality of the developed image attributable to stagnation of the developer.
