PROBLEM TO BE SOLVED: To smooth the flow developer in an image printing area on the surface of a magnet roller and to obtain the image output of high quality with less deterioration by providing a carrying part carrying developer by magnetic force from a 1st stirring and carrying body positioned on a lower side to a 2nd stirring and carrying body positioned on an upper side. SOLUTION: The high-fluidity two-component developer whose fluidity is 65.0sec/50g is stored in a developer container 27 storing the developer. In the container 27, a magnet roller 28 functioning as a developer supply roller supplying required developer is provided so as to freely rotate for plural electrostatic latent image holding bodies 12a, respectively. A screw 29 functioning as a 1st developer stirring body and a screw 30 functioning as a 2nd developer stirring body, which stir and carry the developer, are disposed in parallel behind the roller 28. Meanwhile, a doctor blade 31 regulating the developer on the outer peripheral surface of the roller 28 is provided on the upside of the roller 28. |
