Abstract:
A developing device includes a housing having an opening in a wall thereof, a hollow developing roller, a magnetic pole structure disposed within the developing roller and at least a portion thereof facing the opening in the housing, a gap forming member located within the housing at a location downstream the opening in the housing and forming a first gap with the developing roller and forming a second gap with the housing, and a blocking member arranged in the first gap. The housing and the gap forming member form a first opening and a second opening spaced from the first opening across the second gap between the gap forming member and the housing, such that the first opening is farther from the opening in the wall of the housing than the second opening, and the width of the first opening is larger than that of the second opening.

Claim (Index 1):
A developing device, comprising:\n a housing having an opening in a wall thereof; a developing roller, having a hollow interior portion and an axis of rotation, rotatably arranged within the housing to rotate in a rotation direction about the axis of rotation; a magnetic pole structure disposed within the hollow interior portion of the developing roller, at least a portion thereof facing the opening in the wall of the housing, wherein the developing roller is configured to carry a developer on an outer surface thereof using the magnetic field of the magnetic pole structure; a gap forming member located within, and spaced from, the housing at a location downstream, in the rotation direction of the developing roller, of the opening in the wall of the housing forming a first gap with respect to the developing roller and forming a second gap with respect to the housing; and a blocking member arranged in the first gap, wherein the housing and the gap forming member forma first opening and a second opening spaced from the first opening across the second gap between the gap forming member and the housing, the first opening located farther from the opening in the wall of the housing than the second opening, and the width, in the axis of rotation direction of the developing roller, of the first opening is larger than that of the second opening.
