A developing device for developing, by using a developer, a latent image formed on a surface of an image data forming member including a developer accommodating section for accommodating the developer; a first developer retaining member for receiving the developer from the developer accommodating section and transporting the developer; a second developer retaining member for receiving the developer from the first developer retaining member and making the developer adhere to the latent image formed on the image data forming member; a conductive member opposed to the second developer retaining member with an appropriate space interposed therebetween; a first voltage applying member for applying a voltage between the first developer retaining member and the second developer retaining member; a second voltage applying member for applying a voltage between the second developer retaining member and the surface of the image data forming member; and a third voltage applying member for applying a voltage between the second developer retaining member and the conductive member in order to form an electric field in the space therebetween.

A hologram scanner includes a reproducing light source for generating a collimated reproducing light beam, a hologram disk being adapted to rotate, and a hologram disposed on the hologram disk for deflecting the reproducing light beam by diffraction so as to scan an image surface by the deflected reproducing light beam during a rotation of the hologram disk. The hologram has interference fringes recorded by a mutual interference of an object light of divergent spherical wave and a reference light of divergent spherical wave. The object light is generated by an object light source positioned at a first position apart from a hologram recording plane of the hologram disk, on which the hologram is to be recorded, by a first distance. The reference light is generated by a reference light source positioned at a second position apart from the hologram recording plane by a second distance. The first and second distances are different from each other so that the deflected reproducing light beam is focused on the image surface.
