ABSTRACT:
A method for developing an electrostatic latent image includes the steps of preliminarily charging a toner, supplying the preliminarily charged toner to a resilient developing brush held in resilient contact with a latent image carrier while electrically charging the toner in a toner supplying region, transferring the toner on the resilient developing brush to an image developing region, developing the electrostatic latent image formed on the image carrier with the toner by bringing the resilient developing brush into contact with the latent image carrier and the image developing region, transferring the resilient developing brush from the image developing region to a toner recovering region separate from the toner supplying region after the image has been developed, recovering residual toner from the resilient developing brush in the toner recovering region in order to remove toner density irregularities from the resilient developing brush, and thereafter transferring the resilient developing brush to the toner supplying region for successive image development. Also provided is an apparatus for carrying out the above steps.
