1. An image forming apparatus to and from which a replenishment container accommodating toner is attachable and detachable and which is configured to form an image on a recording material, the image forming apparatus comprising:
an image bearing member;
a developer container configured to accommodate toner;
a developing roller configured to develop an electrostatic image formed on the image bearing member into a toner image by using the toner accommodated in the developer container;
a replenishment port configured to allow replenishment of toner from the replenishment container, which is arranged outside of the image forming apparatus, to the developer container therethrough in a state where the replenishment container is attached to the replenishment port;
an opening/closing portion configured to open the replenishment port in an open position and close the replenishment port in a closed position, the opening/closing portion moving from the closed position to the open position in a case where the replenishment container attached to the replenishment port is rotated;
a locking member configured to move between a restricting position in which the locking member restricts a movement of the opening/closing portion from the closed position to the open position, and an allowing position in which the movement of the opening/closing portion from the closed position to the open position is allowed;
a first display configured to display information related to the toner accommodated in the developer container; and
a second display configured to switch between a first state and a second state different from the first state, the developer container being capable of accepting more toner for replenishment in a case where the second display is in the second state than in a case where the second display is in the first state,
wherein the replenishment container is a squeezable toner pack which is squeezed by the user to promote discharge of toner in the toner pack.
