る。When the opening / closing lid 3 is slid in the direction in which the toner supply port 2 is opened, the holding frame 4 is opened.
At the same time, the container lid of the toner bottle simultaneously slides in the direction of opening the opening. As a result, the opening of the toner bottle and the toner supply port 2 of the toner hopper 1 communicate with each other, and the toner in the toner bottle drops into the toner hopper 1.

トナー飛散がおこる。In the conventional toner replenishing device, the holding frame 4 is provided with an engaging function for engaging with the toner hopper 1, and the engagement is achieved only by placing the toner bottle on the holding frame 4. Since it is released, the engagement with the toner hopper 1 is easily released by pushing from the outside in the vertical direction with a hand or an object, or by vibration or the like. At this time, when the opening / closing lid 3 slides, the toner replenishing port 2 is opened and the toner is scattered.
