In FIG. 1, a developing device 6 includes a two-component developer 5 including a chargeable powder toner and a magnetic powder that frictionally charges the toner, and a photoconductor 9 on which an electrostatic latent image is formed. The developer transport member 4 for supplying and transporting the developer is accommodated therein. The toner replenishing device 1 accommodates the chargeable powder toner 2 and rotates the toner feeding member 3 according to the consumption of the toner in the developing device 6 to feed the toner 2 to the developing device 6 side. Here, in the present invention, a vibration applying device that applies vibration to the toner 2 fed from the toner feeding member 3 between the toner feeding portion (below the toner feeding member 3) of the toner replenishing device 1 and the developing device 6.
