。 A toner hopper is provided outside a developing device that supplies a developer to a latent image formed on a photoconductor to visualize it, and a stirring member that stirs the toner stored therein is provided in the toner hopper, In a two-component developing device of an electrostatic recording device, in which the toner in the toner hopper is supplied to the inside of the developing device by a conveying screw provided from the bottom of the toner hopper to the inside of the developing device, the stirring member is The toner hopper is formed as an impeller with stirring blades attached in a twisted state to a shaft that is substantially orthogonal to the axis of the conveying screw and rotatably supported by the toner hopper.
A two-component developing device characterized in that the stirring blade of the impeller is engaged with the spiral blade of the conveying screw in a worm wheel-to-worm relationship, and the impeller is rotationally driven by rotation of the conveying screw.
