<P>PROBLEM TO BE SOLVED: To provide a developing method and an image forming method for obtaining a high-quality image without causing starvation in a halftone image. <P>SOLUTION: In the developing method including a step of charging toner carried on a developer carrier by pressurizing and regulating the toner with a regulating member and a step of imparting the toner to an electrostatic latent image formed on an image carrier to visualize as a toner image, the toner after pressurized and regulated by the regulating member is controlled to satisfy the following relation when the individual particle size and charged amount of toner particles are measured by a laser Doppler method in an oscillation field in an acoustic alleviation cell. The relation is expressed by (B2-B1)/(A2-A1)<-1, wherein A1 [μm] and B1 [fC] represent the particle size and the charged amount of the charged toner particle in the division that has the largest number proportion in the distribution divided by the measured particle size and the measured charged amount, respectively; A2 [μm] represents the particle size in the division that has the largest particle size in the particle size distribution showing ≥1% number proportion; and B2 [fC] represents the charged amount in the division that has the largest number proportion along the particle size divisions of A2. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
