A developing device comprises a stirring roller 7 having stirring blades 7a for stirring a developer, a developing roller 3 for transferring the developer to an electrostatic latent image, a control member 4 for controlling the amount of developer transferred from the developing roller 3 to the electrostatic latent image, a reflux plate 6 by which the excess developer resulting from control by the control member 4 is flowed back to the stirring roller 7, one end portion of the reflux plate 6 being disposed in the vicinity of the outer periphery of the stirring roller 7, part of the developer stirred by the stirring roller 7 flying toward the reflux plate 6, wherein said one end portion of the reflux plate 6 is disposed at a position remote from the stirring roller 7 over a distance greater then the maximum fly distance of the developer provided by rotation of the stirring roller 7.
