ABSTRACT:
A device for developing an electrostatic latent image includes a developing sleeve and a sponge roller which is in scrubbing contact with the sleeve. Thus, even if non-magnetic, single component toner is used, it is electrically charged due to the scrubbing action and thus electrically attracted to the developing sleeve. A doctor blade is pressed against the developing sleeve and thus the toner is formed into a thin film having sufficient charge and a predetermined thickness. As the developing sleeve further rotates, thus formed thin film is brought to a developing region where the latent image is developed by the thin film of toner. Preferably, the blade is arranged in a particular orientation with respect to the sleeve. The blade may be movably provided so as to be pressed against the sleeve by an appropriate biasing element. The sleeve and the sponge roller may be driven to rotate same or opposite in direction, as desired. The sleeve may be formed to be elastically deformable. The sleeve may be set in oscillation. The blade is preferably comprised of a copolymer of ethylene and tetrafluoroethylene.
