Summary:A developing device includes a container having an opening, a developer roller disposed within the container to supply toner to a photosensitive body through the opening, and an air flow passage. The air flow passage receives air from inside of the container and supplies the air, via an end of the container in a longitudinal direction of the developer roller, to an upstream side, in a rotation direction of the developer roller, of a closest position between the developer roller and the photosensitive body. The air flow passage has an outlet that is aligned with a central area in the longitudinal direction of the developer roller.
