Abstract:
A developing device includes a developing container, a first agitating feeding member, a second agitating feeding member, a first developer delivery portion, a second developer delivery portion, and a toner sensor. The developing container includes a first transport path and a second transport path. The first agitating feeding member and the second agitating feeding member agitate and feed developer. The first developer delivery portion delivers the developer from the first transport path to the second transport path. The second developer delivery portion delivers the developer from the second transport path to the first transport path. The toner sensor is disposed at a part of the first transport path near the first developer delivery portion. A ceiling height of a part of the first transport path facing the first developer delivery portion is larger than a ceiling height of other part of the first transport path.
