Abstract:
1. An image forming method comprising: in a center feed developing system comprising first and second developing rollers and a developing agent distributing member formed between said first and second developing rollers, and using a two-component developing agent consisting mainly of toners and magnetic carriers: wherein said latent image is developed by said first and second developing rollers disposed along the moving direction of said image carrier and rotatable in the mutually opposite directions using said two-component developing agent consisting mainly of toners and magnetic carriers, and said toners are supplied to said latent image on said image carrier by said first and second developing rollers, wherein the moving direction of said first developing roller is opposite to the moving direction of said image carrier in a developing area, and a peripheral speed ratio (S wherein the moving direction of said second developing roller is the same as the moving direction of said image carrier in a developing area, and a peripheral speed ratio (S wherein a plurality of shape coefficients SF said shape coefficients SF 1 , SF 2 respectively satisfying the following conditions:
