Patent ID: 10303086

Abstract:
A developer supply container includes a developer accommodating portion 2a for accommodating toner, a developer supply opening 5b for discharging the toner accommodated in the developer accommodating portion 2a from the developer supply container 1, a feeding portion 2b for feeding the toner in the developer accommodating portion 2a toward the developer supply opening 5b, a rotatable drive receiving portion 7a for receiving a rotational force for rotating the feeding portion 2b, and a holding projection 4h held by a holding mechanism 304 provided in the developer supply container 1 to determine a position of the developer supply container 1, wherein the developer supply opening 5b is disposed between the drive receiving portion 7a and the holding projection 4h. By this, a stability of connection between the discharge opening of the developer supply container and the receiving port of the image forming apparatus side is improved.
