Description of the Related Art In image forming apparatuses such as copiers and printers, there are two-component developers containing toner and carrier for visualizing an electrostatic image, and one-component developers containing only magnetic toner or non-magnetic toner. In any case, it is necessary to replenish the developer (hereinafter referred to as toner) to the toner storage layer of the developing device in the process of using it. These toners are in the form of powder having fluidity, and the toner has a particle size of micron unit and is very fine. Therefore, when an operator replenishes the toner to the toner storage layer, the toner soaring from the opening of the toner replenishing device Is scattered in the air. As a result, there are adverse effects such as contamination inside and outside the apparatus and a worker sucking the scattered toner.

トナーの量が多くなる。In such a configuration, when the toner replenishing device is opened and the toner bottle is tilted and swung toward the opening on the side surface of the device main body to replenish the toner reservoir, the toner is replenished. When the toner is dropped into the storage tank, a phenomenon occurs in which toner is scattered in the storage tank. In particular, the smaller the amount of residual toner in the toner storage tank, the larger the space in the toner storage tank, resulting in more remarkable toner scattering. The larger the area of the opening of the replenishing device, the more the toner in such a state is scattered into the air outside the replenishing device, and the amount of the toner increases.
