Patent ID: 7835672

Claim:
A developing device comprising: a developer carrier that rotates while carrying a developer on a surface thereof; a first developer containing chamber that contains the developer to be supplied to the developer carrier; a second developer containing chamber that has a bottom face disposed at a position lower, in a gravitational direction, than a bottom face of the first developer containing chamber; a first inflow section that allows the developer to flow from the second developer containing chamber into the first developer containing chamber; a second inflow section that allows the developer to flow from the first developer containing chamber into the second developer containing chamber; a first conveyance member that is disposed in the first developer containing chamber and conveys the developer contained in the first developer containing chamber in a first developer conveyance direction going from the first inflow section toward the second inflow section; and a second conveyance member that is disposed in the second developer containing chamber and conveys the developer contained in the second developer containing chamber in a second developer conveyance direction going from the second inflow section toward the first inflow section, wherein the second developer containing chamber is formed so that in a range corresponding to the first inflow section, an area of a cross section, perpendicular to the second developer conveyance direction, of the second developer containing chamber decreases along the second developer conveyance direction, wherein the second developer containing chamber includes an inclination portion that is formed in the range corresponding to the first inflow section, the inclination portion is inclined so that the bottom face of the second developer containing chamber becomes higher along the second developer conveyance direction.
