摘要： In a consumables ordering system, an image forming apparatus notifies a management system about a consumable whose remaining quantity is under a specific threshold. When a consumable whose remaining quantity is under the threshold is autonomously notified from the image forming apparatus, the management system checks the consumable whose remaining quantity is under the threshold in a specific image forming apparatus other than an autonomously notifying apparatus (S122), and notifies the autonomously notifying apparatus about the consumable autonomously notified from the autonomously notifying apparatus, and ordering information as information necessary for placing an order for the consumable checked in S122 (S129). The autonomously notifying apparatus displays the ordering information notified from the management system, and places an order for the consumable for which the ordering information is displayed in response to an instruction.

摘要： An image forming apparatus (10) according to an aspect of the present invention includes a toner container (3), a support member (61), a lock member (65), a lock removing portion (120), and a moving mechanism (659, 660). The toner container is configured to be attached to an attachment position set in an apparatus main body (11). The support member supports the toner container so that the toner container can be moved between the attachment position and a detachment position that is separated from the attachment position toward a predetermined first surface of the apparatus main body. The lock member is provided on the support member in such a way as to be movable in a first direction that extends along the first surface, and is displaced between a lock position where the lock member is engaged with the toner container so that the toner container is locked to the attachment position, and a removal position where a lock of the toner container is removed. When a predetermined removal condition is satisfied, the lock removing portion moves the lock member from the lock position to the removal position to remove the lock of the toner container. The moving mechanism moves the toner container toward the detachment position when the lock removing portion removes the lock.
