Patent attributes
An electrophotographic image forming apparatus and a developing method thereof are provided. The electrophotographic image forming apparatus includes an image carrier body on which an electrostatic latent image is formed, a developing roller which faces the image carrier body and supplies toner to the electrostatic latent image formed on the image carrier body, and an anti-toner-dispersion element which faces an outer circumferential surface of the image carrier body between an exposing section where the electrostatic latent image is formed and a developing section where the electrostatic latent image is developed by the developing roller. A collection bias is applied to the anti-toner-dispersion element to collect dispersed toner from the developing roller.
