Abstract (en)
An image forming apparatus (10) for forming an image on an image bearing member (32) includes a developing unit (38) for developing a latent image formed on the image bearing member (32). The developing unit (38) includes a developing roller (52) for transporting a developer to the image bearing member, a blade (58) for forming a layer of the developer on the developing roller (52) and a preventing member for covering the layer of the developer formed on the developing roller so as to prevent the developer from leaking outside the developing unit. By a simple construction, the image forming apparatus of the present invention prevents developer from leaking outside the developing unit when the developer is mechanically scraped up by a blade and is transported to the image bearing member by the developing roller. <IMAGE>
