<p>PROBLEM TO BE SOLVED: To stably obtain a color image lessened in the image quality change in the lapse of time, when continuously used, by minimizing influence to the image quality as a result of electrostatic charge deterioration of the developer. SOLUTION: This method for the image forming is, allowed to visualize at least, a latent image formed on the latent image carrier by developing with use of yellow toner, the magenta toner and the cyan toner. In this case, the method is allowed to respectively make the volume average particle diameter of the toner below 7μm, the compression ratio of the toner below 0.43, differential of the compression ratio of the yellow toner, the magenta toner and the cyan toner below 0.03, and the ratio between the maximum and minimum charge quantity of the yellow toner, the magenta toner and the cyan toner 1.00 to 1.15, and moreover the average particle size of carriers in the range between 20 to 50μm, and furthermore processing speed beyond 200 mm/sec.</p> |
