<P>PROBLEM TO BE SOLVED: To provide a developing device whose stirring capability of a developer by a transporting member for stirring and transporting the developer in a developing container is increased, a cartridge, and an image forming device. <P>SOLUTION: The developing device has the carrying member 14 wherein the angle Θ (°) formed by an axis of rotation 14a and horizontal satisfies 2°≤Θ≤10° in a stirring chamber 22 and has the configuration satisfying Ha (mm)+2 (mm)≤Hb (mm) (where 25 (mm)≤Dv (mm)≤100 (mm)) when a first perpendicular plane V 1 inclusive of an intersection point A intersected by the front end of the transporting member 14b and a developer face and a second perpendicular plane V 2 inclusive of an intersection point B intersected by the front end of the transporting member 14b and a developer face are assumed, and when the horizontal direction distance of the first perpendicular plane V 1 and the second perpendicular plane V 2 is defined as Dv (mm), the height in the perpendicular direction of the intersection point A with respect to the central position P of the axis of rotation 14a inside the first perpendicular plane V 1 as Ha (mm), and the height in the perpendicular direction of the intersection point B with respect to the central position Q of the axis of rotation 14a inside the second perpendicular plane V 2 as Hb (mm). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
