comprising a shielding portion for shielding said communication port when said shutter is in a resealing position. ### Claim 9 (depends on 1) A developer supply container according to claim 1, further comprising a removal engaging portion for displacing said developer receiving portion in a direction of spacing from said developer supply container with a dismounting operation of said developer supply container. ### Claim 10 (depends on 9) A developer supply container according to claim 9, wherein said removal engaging portion displaces said developer receiving portion with the dismounting operation of said developer supply container to effect a resealing operation of said developer receiving portion. ### Claim 11 (depends on 9) A developer supply container according to claim 9, wherein said removal engaging portion displaces said developer receiving portion in a direction crossing with the dismounting direction of said developer supply container. ### Claim 12 (depends on 1) A developer supply container according to claim 1, further comprising a drive inputting portion for receiving a driving force from said developer receiving apparatus and a pump portion so that an internal pressure of said developer accommodating portion alternately and repetitively changes between a pressure lower than an ambient pressure and a pressure higher than the ambient pressure, wherein said developer accommodating portion includes a rotatable developer feeding chamber for feeding the developer, and a developer discharging chamber provided with an opening for permitting discharging of the developer and held by said developer receiving apparatus so as to be non-rotatable relative to said developer receiving apparatus, and wherein said engaging portion is integral with said developer discharging chamber. ### Claim 13 (depends on 1) A developer supplying system comprising a developer supply container according to claim 1, and a developer receiving apparatus to which said developer supply container is detachably mounted, said system further comprising a developer receiving portion for receiving the developer from said developer supply container, wherein said developer receiving portion is displaceable toward said developer supply container with the mounting operation of said developer supply container to establish a connected state with said developer supply container. ### Claim 14 A developer supply container for supplying a developer through a developer receiving portion displaceably provided in a developer receiving apparatus to which said developer supply container is detachably mountable, said developer supply container comprising: a developer accommodating portion for accommodating a developer; and an inclined portion, inclined
