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 to

Abstract: A two-component toner is directly supplied to a brush which is cyclically transferred while in resilient contact with a latent image carrier for developing an electrostatic latent image on the latent image carrier. After the image has been developed by the toner, residual toner is directly recovered from the brush for uniformizing the toner density on the brush.

Abstract: A magnetic brush type developing device using a one-component system developing agent suitable for use with electrophotographic copying apparatus including a scraper having a magnetic wire disposed in close proximity to a developing sleeve serving as means for agitating and mixing a developing agent used for developing and a fresh supply of the developing agent fed to supplement the developing agent consumed by developing. The scraper includes a nonmagnetic plate provided with a plurality of stays in the form of a comb disposed on a side thereof facing the developing sleeve, and a magnetic wire mounted on the forward end of the stays and arranged in a magnetic field generated by a magnet disposed in the developing sleeve. The magnetic wire and the developing sleeve are spaced apart from each other by a predetermined gap.
