Abstract

PURPOSE:To delicately vary an image by varying a resistance value of a developer which adheres to a spike rise forming plate, by an image adjusting means. CONSTITUTION:An image adjusting means for adjusting the quantity of a developer 2 which adheres to a spite rise forming plate 24 is constituted so that the spike rise forming plate 24 can be turned and fixed freely in the rotational direction of a magnet body 21 centering around its turning center. In such a state, when the magnet body 21 is rotated, the developer 2 being in a state of a spike rise along a line of magnetic force by magnetic force of magnets N, S also moves as the magnet body 21 rotates. In such astate, in case of adjusting an image by changing the quantity of the developer 2 which adheres to the spike rise forming plate 24, a resistance value of the developer 2 is varied by the image adjusting means. In such a way, a delicate adjustment of the image can be executed easily.
