Developing device having an air discharge path

A developing device comprising:

• a developer transport path;
• a developing roller mounted in the developer transport path;
• a discharging unit extending from the developer transport path in a length direction of the developing roller, the discharging unit comprising an air outlet to discharge air and a developer discharge outlet to discharge the developer;
• a separating member mounted in the discharging unit and configured to separate an inner portion of the discharging unit into an air discharge path connecting the developer transport path and the air outlet, and a developer discharge path connecting the developer transport path and the developer discharge outlet;
• an agitating member in the developer transport path, the agitating member to transport the developer to the developer discharge outlet,
• wherein the agitating member extends into an inner portion of the developer discharge path, and
• wherein the separating member elastically contacts the first agitating member.

A developing device comprising:

• a developer transport path to transport and agitate a developer;
• a developing roller mounted in the developer transport path;
• a discharging unit extending from the developer transport path in a length direction of the developing roller, the discharging unit comprising a developer discharge outlet to discharge the developer, wherein the discharging unit further comprises a developer discharge path connecting the developer transport path and the developer discharge outlet, the developer to flow from the developer transport path through the developer discharge path to the developer discharge outlet;
• and
• an air blocking member partially blocking air from flowing from the developer transport path into the developer discharge path.
