Claim 19:
20. An image forming apparatus to and from which a replenishment container accommodating toner is attachable and detachable and which is communicable with an information processing apparatus comprising a first display and is configured to form a toner 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 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; and
a controller configured to, in a case where a replenishment operation, in which toner is supplied from the replenishment container to the replenishment port, is performed when the second display is in the second state, switch the second display from the second state to the first state and perform a display processing of displaying, on the first display, a printable sheet number corresponding to an amount of toner accommodated in the developer container after the replenishment operation,
wherein the replenishment container is a squeezable toner pack which is squeezed by the user to promote discharge of toner in the toner pack.
