Abstract
A developing device includes a developer container; a developer holding body including a magnet member and a substantially cylindrical member; a transport member including a rotating shaft and a substantially spiral transport blade; a layer-thickness regulating member; and an interrupting member that is arranged between the developer holding body and the transport member, that intersects with a first virtual plane passing through a facing position between the regulating member and the developer holding body and being adjacent to a rotation locus of a radial-direction outer edge of the transport blade at a position at which a speed in a circumferential direction of the transport blade has a speed component toward the regulating member, and a second virtual plane passing through rotation centers of the developer holding body and transport member, and that interrupts movement of the developer pushed and moving in the radial direction of the transport blade.
