Abstract
A developing device includes a case for housing a developer, a magnetic roller, an agitating member, a layer thickness restricting member, an auxiliary developer storing portion and a plate-like flexible member. The magnetic roller includes a rotary shaft and magnetically carries the developer on a circumferential surface. The agitating member includes a shaft center and a screw forming portion arranged around the shaft center and agitates and conveys the developer while rotating. The layer thickness restricting member restricts the layer thickness of the developer to a predetermined thickness. The auxiliary developer storing portion faces the circumferential surface of the magnetic roller at a side upstream of the layer thickness restricting member in a rotating direction of the magnetic roller. The plate-like flexible member extends toward the circumferential surface of the magnetic roller and forms a wall surface on an upstream side of the auxiliary developer storing portion.
