Claims

[Scope of utility model registration request]

In an electrophotographic printing device using a two-component developer consisting of toner and a magnetic carrier for transporting the toner, a box in which the developer is stored, a magnet roll provided within the box facing a photoreceptor; a developer supply wheel that is provided near the magnet roll and rotates to supply developer to the magnet roll; a spiral pipe that is provided inside the box and has a diameter that gradually decreases from the top to the bottom; A chute □ is provided near the magnet roll to guide the developer to be picked off to the top of the pipe, and a dispersion mechanism is provided below the pipe to almost evenly distribute the developer that is about to fall. Characteristic developing device.
