A toner filling apparatus includes a filling tank, a toner filling path forming member, a toner fluidizing unit, a filling path opening/closing unit and a container room sucking unit. The toner filling path forming member is in communication with the filling tank and forms a toner filling path connected to the toner container. The container room sucking unit sucks air from the toner container through a filter member which is impermeable to the toner but permeable to air. When the toner fluidizing unit fluidizes the toner in the filling tank and the filling path opening/closing unit opens the toner filling path so as to load the toner to the toner container, the container room sucking unit reduces a pressure in the toner container to a negative pressure so as to draw in the toner into the toner container.
