Claims

[Scope of Claim for Utility Model Registration] 1. A housing with an open top and a toner cartridge removably attached to the upper end of the housing form a sealed toner supply chamber. In a developing device of an electrophotographic recording device, an arm is provided which rotates as a rotor, and the toner in a toner supply chamber is agitated by the rotational motion of the arm, and the toner is sent to a developing chamber that houses a developing roller and the like. , a developing device of an electrophotographic recording device, the length of which is such that its tip comes into contact with the inner surface of the toner cartridge. 2. The arm is formed into a U-shape by bending one rod-like member, and its two free ends are fixed to the horizontal shaft as base ends, and the tip shaft has an inner diameter larger than the diameter of the shaft. A developing device for an electrophotographic recording device according to claim 1, which is formed by fitting a cylindrical member having a cylindrical member. 3. The developing device for an electrophotographic recording apparatus according to claim 1, wherein the toner cartridge has an inner surface formed into a curved surface having a radius substantially equal to the rotation radius of the arm. .
