Abstract
A toner container detachably mountable to an image forming apparatus, includes a main body for containing toner; a sealing portion for sealing the toner discharge opening; locking projections for snap fitting engagement with holes provided in a cylindrical member of an image forming apparatus, wherein the projections receive from the cylindrical member unsealing forces for unsealing the toner discharge opening by a relative movement between the sealing portion and the toner container, wherein a number of the locking projections is larger than a number of ribs provided between the holes of the cylindrical member.

21. A toner supply container detachably mountable to an image forming apparatus, said container comprising:
-
a container body having an inner space configured and positioned to contain toner; a feeding portion configured and positioned to feed the toner in said container body to discharge the toner out of said container body; and a coupling member configured and positioned to engage with a hollow cylindrical member provided in the image forming apparatus, wherein said coupling member including; an engaging portion configured and positioned to engage with a hole formed in a peripheral portion of the cylindrical member to receive a rotational force from the cylindrical member, a supporting portion configured and positioned to support said engaging portion, said supporting portion being displaceable substantially radially outwardly to establish engagement of said engaging portion with the hole of the cylindrical member by a relative movement between the cylindrical member and said coupling member in a direction of overlapping therebetween; and a displacing force receiving portion, disposed at a position on said supporting portion closer to said container body than said engaging portion with respect to a direction of overlapping therebetween, configured to receive, from a slidable hollow member provided in the image forming apparatus outside the cylindrical member, a displacing force for displacing said engaging portion substantially radially inwardly to permit a relative movement for disengagement between the cylindrical member and said coupling member in a direction opposite to the direction of overlapping. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A toner supply system including a toner supply apparatus and a toner supply container for supplying toner to said toner supply apparatus, said system comprising:
-
said toner supply apparatus including; a mounting portion configured and positioned to detachably mount said toner supply container; a hollow cylindrical member, provided with a hole formed in a peripheral portion thereof, configured and positioned to apply a rotational force; and a hollow member configured and positioned to apply a displacing force, said hollow member being slidable outside said cylindrical member, said toner supply container including; a container body having an inner space configured and positioned to contain toner; a feeding portion configured and positioned to feed the toner in said container body to discharge the toner out of said container body; and a coupling member configured and positioned to engage with said cylindrical member; said coupling member including; an engaging portion configured and positioned to engage with said hole of said cylindrical member to receive the rotational force from said cylindrical member, a supporting portion configured and positioned to support said engaging portion, said supporting portion being displaceable substantially radially outwardly to establish engagement of said engaging portion with said hole by a relative movement between said cylindrical member and said coupling member in a direction of overlapping therebetween; and a displacing force receiving portion, disposed at a position on said supporting portion closer to said container body than said engaging portion with respect to the direction of overlapping, configured to receive, from said hollow member, the displacing force for displacing said engaging portion substantially radially inwardly to permit a relative movement for disengagement between said cylindrical member and said coupling member in a direction opposite to the direction of overlapping. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
