Abstract
A toner replenishing device is improved to prevent unexpected dropping of toner when attaching a toner storage cartridge to a toner receptacle of a developer and detaching it therefrom. The cartridge is easily attached to the developer and is hooked in place thereto when a sheet sealing an open end of the cartridge is removed. The cartridge easily is detached from the developer by the operation of a cam portion engaging with a hooking member as a result of displacement of the cartridge by a distance equal to the thickness of the sheet and a sheet tearing member which previously are removed from the cartridge.
