Abstract:
A developing device includes a housing having an opening in a wall thereof, a developing roller rotatably arranged within the housing, and a magnetic pole structure, wherein the developing roller is configured to carry a developer on an outer surface thereof using the magnetic force of the magnetic pole structure. The developing device further includes 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, a blocking member arranged in the first gap, and a guide section configured to guide airflow passing through the second gap in a general direction toward the developing roller.

Claim (Index 2):
The developing device according to  claim 1 , wherein\n a first virtual straight line passing through a rotation center of the developing roller and a second virtual straight line along a surface of the guide section that guides the airflow in the general direction toward the developing roller, intersect at an outer surface of the developing roller, and an angle formed by the first virtual straight line and the second virtual straight line is greater than or equal to 30 degrees and less than or equal to 90 degrees.
