Abstract
PURPOSE:To prevent an uneven development, and to obtain a satisfactory image by dispersing magnetic powder to a spike rise forming plate. CONSTITUTION:When a developer 2 moves to the end part of a circular arc-like spike rise forming plate 24 as a magnet body 21 rotates, it is scraped by a scraping end 24a of the spike rise forming plate 24, and goes to a spike rise state on the spike rise forming plate 24 by magnetic force of magnets N, S. Subsequently, a photosensitive body 2 and the developer 2 come into contact with each other, the developer 2 is transferred to an electrostatic latent image formed on the photosensitive body 23, and the development is executed. In such a case, since magnetic powder 24d is dispersed to the spike rise forming plate 24, a magnetic field to the magnets N, S is dispersed, and developing pressure of the developer 2 generated due to a difference of magnetic force in the radial direction of the magnet body 21 is corrected uniformly. In such a way, an uneven development is prevented, and a satisfactory image is obtained.
