Abstract
A coupling member to be engaged by snap hooking with an engaging hole provided to a driving portion of a main assembly of an image forming apparatus is provided with a snap hook portion at an entire peripheral surface thereof so as to prevent idle running at the time of start of rotation of the driving portion to obviate an impingement shock when the coupling member is caused to impinges on a rib provided to the driving portion.
Claims18
A developer supply container detachably mountable to an image forming apparatus including a hollow cylindrical member having at least one hole and at least one rib formed between circumferential ends of one hole or between adjacent ones of a plurality of holes, comprising:
- a container body for containing toner;
- a coupling member including a plurality of hooks for hooking engagement with the at least one hole of the cylindrical member by relative motion between the cylindrical member and said coupling member in a direction of overlapping therebetween, and at least one hook of said plurality of hooks receiving a rotational force by abutment of the at least one rib to discharge the developer out of said container body,
- wherein said hooks are provided at an entire circumferential surface of said coupling member so as to establish an engageable relationship between the cylindrical member and said coupling member in a rotation direction of the container body by the relative motion.
A developer supply container detachably mountable to an image forming apparatus including a hollow cylindrical member having at least one hole and at least one rib formed between circumferential ends of one hole or between adjacent ones of a plurality of holes, comprising:
- a container body for containing toner;
- a coupling member including a plurality of hooks for hooking engagement with the at least one hole of the cylindrical member by relative motion between the cylindrical member and said coupling member in a direction of overlapping therebetween, and at least one hook of said plurality of hooks receiving rotational force by abutment of the one rib to discharge the developer out of said container body,
- wherein said hooks are provided at an entire circumferential surface of said coupling member so that each of the at least one rib is sandwiched between two hooks in a rotation direction of the container body by the relative motion.
A coupling member of a developer supply container which is detachably mountable to an image forming apparatus including a hollow cylindrical member having at least one hole and at least one rib formed between circumferential ends of one hole or between adjacent ones of a plurality of holes, comprising:
- a coupling portion including a plurality of hooks for hooking engagement with the at least one hole of the cylindrical member by relative motion between the cylindrical member and said coupling portion in a direction of overlapping therebetween, and at least one hook of said plurality of hooks receiving rotational force by abutment of the one rib to discharge the developer out of said container body,
- wherein said hooks are provided at an entire circumferential surface of said coupling member so as to establish an engageable relationship between the cylindrical member and said coupling member in a rotation direction of the container body by the relative motion.
A coupling member of a developer supply container which is detachably mountable to an image forming apparatus including a hollow cylindrical member having at least one hole and at least one rib formed between circumferential ends of one hole or between adjacent ones of a plurality of holes, comprising:
- a coupling portion including a plurality of hooks for hooking engagement with the at least one hole of the cylindrical member by relative motion between the cylindrical member and said coupling portion in a direction of overlapping therebetween, and at least one hook of said plurality of hooks receiving rotational force by abutment of the one rib to discharge the developer out of said container body,
- wherein said hooks are provided at an entire circumferential surface of said coupling member so that each of the at least one rib is sandwiched between two hooks in a rotation direction of the container body by the relative motion.
