A toner supplying device which supplies toners contained in a toner
container to a developing device is disclosed. The toner supplying device
includes a toner tank which stores the toners discharged from the toner
container, a toner carrying section which carries the toners stored in
the toner tank, a toner dropping route which causes the toners carried by
the toner carrying section to drop into the developing device by toner's
own weight, a control unit which controls an amount of the toners to flow
into the toner dropping route from the toner carrying section, and a
stirring member which stirs the toners staying at a region between the
toner tank and the toner carrying section.
