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 19):
An adaptor for forming an air flow recirculation path in the housing of a developer cartridge of a multi-functional peripheral having a developing roller having an axis of rotation disposed adjacent to an opening in an enclosure wall thereof, the enclosure wall further including a second opening for receipt of the adaptor therein, comprising:\n a main body configured to be receivable within the second opening of an enclosure wall of the housing of a developer cartridge and having a longitudinal length and a first width; a gap forming member spaced from, and supported by, the main body, the gap forming member extending in the longitudinal length direction of the main body and having a second width smaller than the width, with the main body, forming a gap therebetween having first and second openings spaced from each other by the second width; and a plurality of ribs extending from the main body, the ribs spaced from each other in the longitudinal length direction of the main body and each extending along the main body in a direction substantially orthogonal to the longitudinal length direction of the main body, wherein the gap includes a first opening between the main body and the gap forming member and a second opening between the main body and the gap forming member, the first and second openings extending in the length direction of the main body and spaced from each other across the width of the gap forming member, and the length of the first opening in the length direction of the main body is greater than the length of the second opening in the length direction of the main body.
