Abstract

A developer supply container detachably mountable to a developer receiving apparatus, the developer supply container includes an accommodating portion for accommodating a developer; a discharge opening for discharging the developer accommodated in the accommodating portion from the developer supply container; a developer feeding portion for feeding the developer in the accommodating portion toward the discharge opening; a rotatable drive receiving portion for receiving a rotational force; a drive transmitting portion for transmitting the rotational force received by the drive receiving portion to the feeding portion; a portion-to-be-detected for detecting rotation of the drive receiving portion; a contact surface for contacting a rotatable member provided in the developer receiving apparatus; wherein the drive receiving portion, the portion-to-be-detected and the contact are formed integrally.

Claims

1. A developer supply container comprising:

a developer accommodating body configured to contain developer;

a developer discharging body in fluid communication with the developer accommodating body, the developer discharging body having a discharge opening to discharge the developer from the developer discharging body, with the developer accommodating body being rotatable about a rotational axis relative to the developer discharging body;

a gear portion rotatable about the rotational axis integrally with the developer accommodating body; and

a rotatable portion integrally molded with the gear portion,

wherein the rotatable portion is provided with a circumferential surface extending along an imaginary circle about the rotational axis, the circumferential surface including an arcuate surface portion extending along the imaginary circle and a recessed surface portion recessed from the imaginary circle toward the rotational axis.

2. The developer supply container according to claim 1, wherein the discharge opening provided in a bottom portion of the developer discharging body to discharge the developer from the developer discharging body to an outside of the developer supply container at the bottom portion.

3. The developer supply container according to claim 1, wherein a plurality of such recessed portions are provided.

4. The developer supply container according to claim 1, wherein a plurality of such arcuate portions are provided.
