Abstract
A developing device includes a developing roller supplying toner to the photoreceptor and a toner layer regulatory member regulating the layer thickness of toner supported on the surface of the developing roller. The toner layer regulatory member has flexible sheets abutting the developing roller and a holder holding the flexible sheets. The multiple flexible sheets are formed along the axial direction of the developing roller and arranged side by side across the circumferential direction of the developing roller. Each flexible sheet has a projected end as a free end which spreads across the length of the developing roller and projects toward the developing roller while the other end side is held as a supported end by the holder. The sheet holder has depressions for holding the flexible sheets in a movable manner.
