Abstract
A developer supply container (1) detachably mountable to a hollow portion of a rotatable photosensitive member (100) provided in a electrophotographic image forming apparatus, the container including a rotatable container body having an inner space for containing a developer; a feeding portion (5) for feeding the developer in the container body with a rotation of the container body to discharge the developer out of the container body; and a engageable portion (3a) which is engageable with the photosensitive member so that container body is rotated integrally with the photosensitive member by a rotational driving force received from a driving member (104) provided in the electrophotographic image forming apparatus.
Claims11
A developer supply container detachably mountable to a hollow portion of a rotatable photosensitive member provided in an electrophotographic image forming apparatus including a driving member, said container comprising:
- a rotatable container body having an inner space configured to contain a developer;
- a feeding portion configured and positioned to feed the developer in said container body in an axial direction of said container body with a rotation of said container body to discharge the developer out of said container body;
- a driving force receiving portion engageable with the driving member and configured and positioned to receive a rotational driving force for rotating said container body from the driving member;
- and
- a driving force transmitting portion, engageable with the photosensitive member and configured and positioned to transmit the rotational driving force received by said driving force receiving portion to said photosensitive member.
A developer supply system of an electrophotographic image forming apparatus comprising:
- a photosensitive member having a hollow portion;
- a driving member configured and positioned to apply a rotational driving force;
- and
- a developer supply container detachably mountable to said hollow portion of said photosensitive member, said developer supply container including:
- a rotatable container body having an inner space configured to contain developer;
- a feeding portion configured and positioned to feed the developer in said container body in an axial direction of said container body with a rotation of said container body to discharge the developer out of said container body;
- a driving force receiving portion engageable with said driving member and configured and positioned to receive the rotational driving force for rotating said container body from said driving member;
- and
- a driving force transmitting portion engageable with said photosensitive member and configured and positioned to transmit the rotational driving force received by said driving force receiving portion to said photosensitive member.
