ABSTRACT:
An image forming apparatus such as a printer or copier includes a photoreceptor for holding a latent image; a charger for charging the photoreceptor; an exposure unit such as an LED array for exposing the photoreceptor with light so as to form a latent image on the photoreceptor; and a developer placed in the vicinity of the photoreceptor, for developing the latent image with a developing agent so as to form a developing agent image on the photoreceptor. The developer includes a developing sleeve for holding the developing agent on its surface and a transferor for transferring the developing agent image on the photoreceptor to a recording medium. A cleaner is provided for cleaning a residual developing agent on the photoreceptor after the developing agent image is transferred to the recording medium and a purge control unit is provided for purging foreign matter from the developing agent on the developing sleeve. The purge control unit includes an attraction member for attracting foreign matter from the developing sleeve.
