Abstract:
A toner supply container, detachably mountable to a main assembly of an image forming apparatus, for supplying toner to the main assembly, said container comprising:a main body for accommodating the toner; a discharging opening for permitting discharging of the toner accommodated in said main body; a container shutter member for opening and closing said discharging opening; a rotatable member rotatably supported by said main body including a drive transmitting portion for engaging with a rotational force transmitting means provided in the main assembly to transmit a rotational force to the rotational force transmitting means; and a rotational force receiving portion for receiving the rotational force from the rotational force transmitting means through engagement with the rotational force transmitting means, wherein said container shutter member is provided with a force for opening and closing said discharging opening by the rotational force received by said rotational force receiving portion, wherein when said toner supply container is not mounted to the main assembly, said rotatable member is rotatable relative to said main body between a first position in which said discharging opening is maintained closed and a second position in which said discharging opening is maintained closed, and which is away from the first position in a rotational direction thereof for opening said container shutter member by a predetermined rotational angle, and wherein said rotatable member is provided with a contact portion, which is contacted by the main assembly to direct said rotatable member to the second position when said drive transmitting portion and the rotational force transmitting means are engaged to mount said container to the main assembly.
