Claim 0:
1. A developer supply container configured to accommodate developer, the developer supply container comprising:
a developer discharging portion that is provided with a discharge passageway extending to outside of the developer supply container, with the discharge passageway configured to discharge the developer accommodated in the developer supply container;
a feeding portion configured to be rotatable relative to the developer discharging portion about a rotational axis to feed the developer to the discharge passageway;
a track provided outside of the developer discharging portion with respect to a first plane that (i) is parallel to the rotational axis of the feeding portion and (ii) passes through the discharge passageway; and
a shutter provided with a shutter opening configured to permit discharge of the developer from the discharge passageway, the shutter being supported by the developer discharging portion so as to be slidable between an open position in which the shutter opening and one end of the discharge passageway are in fluid communication with each other and a closed position in which the end of the discharge passageway is closed by the shutter, the shutter including a recessed portion on an outer side of the shutter,
wherein, when the developer supply container is oriented with the one end of the discharge passageway positioned at a bottom side of the developer discharging portion, (i) the track and the shutter are positioned below a horizontal plane that includes the rotational axis, and (ii) the recessed portion includes an inclined surface that is inclined relative to a horizontal plane, with the inclined surface surrounding the shutter opening and being inclined such that on a second plane that is normal to the rotational axis and passes through the discharge passageway and the shutter opening, the inclined surface is closer to the track on the one side than a part of the developer discharging portion that corresponds to the track on the other side of the developer discharging portion in a state that the shutter opening and one end of the discharge passageway are in fluid communication with each other.
