Abstract

An image forming apparatus including a rotatable developer container, a receiving device which receives the container and is inserted in a direction along a rotational axis of the container and which receives the developer discharged from the container when the container is in a first position, and a regulating member provided on the container. The regulating member prevents, during transportation of the image forming apparatus, the container from moving to the first position from a second position which is upstream of the first position with respect to an inserting direction of the container and in which the developer is not discharged from the container.

Claims24

Dependent claims

An image forming apparatus comprising:

a developer container configured to contain a developer, said developer container including a discharge portion for discharging the developer;
a receiving portion configured to receive the developer discharged from said discharge portion;
a mounting portion configured to mount said developer container at a first position where the developer is supplied to said receiving portion from said discharge portion;
a cover capable of opening and closing;
an inserting portion inserted with said developer container to mount said developer container to said mounting portion;
and
a regulating member attachably and detachably provided on said developer container, said regulating member being configured to regulate a relative position of said developer container to said mounting portion to that said developer container is confined at a second position which is upstream of the first position with respect to an inserting direction of said developer container inserted into said inserting portion and where the developer is not supplied to said receiving portion from said discharge portion,
wherein in a state that said regulating member is not attached to said developer container, and said developer container is mounted at the first position, said cover is capable of closing said inserting portion, and
in a state that said regulating member is attached to said developer container, and said developer container is confined at the second position, said cover is capable of closing the inserting portion.

an inserting portion inserted with said developer container to mount said developer container to said mounting portion;
a regulating member attachably and detachably provided on said developer container, said regulating member being configured to regulate a relative position of said developer container to said mounting portion so that said developer container is confined at a second position which is upstream of the first position with respect to an inserting direction of said developer container inserted into said inserting portion and where the developer is not supplied to said receiving portion from said discharge portion;
and
a retracting mechanism configured to retract said regulating member,
wherein in a state that said regulating member is not attached to said developer container and said developer container is mounted at the first position, said cover is capable of closing said inserting portion, and
in a state that said regulating member is attached to said developer container and said developer container is confined at the second position, said cover is capable of closing said inserting portion.
