摘要： A developer container 1 includes (i) a developer vessel 2, having a cylindrical shape, that carries and discharges toner contained therein through its first discharge opening 31 while the developer vessel 2 is being driven to rotate, and (ii) a developer supply section 3 which (a) supports the developer vessel 2 such that the developer vessel 2 can rotate, (b) temporarily stores the toner discharged from the first discharge opening 31, and (c) discharges the toner outside of the developer supply section 3 from a second discharge opening 5. The first discharge opening 31 is formed in an inclined surface 31a of an edge part of the developer vessel 2. The inclined surface 31a inclines, upstream of a direction in which the toner is carried along a shaft line L1, so as to be at angles with a surface perpendicular to the shaft line L1.
