Appeal No. 1996-3506
Application 08/178,439
photosensitive body means;
conductive contacting type charger means for
producing an electrically-charged area on said photosensitive
body means;
optical writing means for forming an electrostatic
latent image on the electrically-charged area of said body
means;
developing means for electrostatically developing
the electrostatic latent image of said body means as a charged
visible image with an electrostatically-charged one-component
developer; and
transferring means for electrostatically
transferring the charged visible image developed by said
developing means from said body means to a recording medium,
wherein said developing means includes a conductive
developing roller member for entraining the developer to form
a developer layer therearound and for bringing the developer
layer to said body means for the development of the latent
image, a conductive regulating blade member resiliently
engaged with said developing roller for uniformly regulating a
thickness of the developer layer formed therearound, and
charge injection effect means for electrically charging the
developer layer by applying a developer bias voltage to said
conductive developing roller member and electric energy to
said regulating blade member, and
wherein said transferring means includes a
conductive transfer roller member in contact with said body
means, and an electric source for applying an electric energy
to said conductive transfer roller member to give the
recording medium an electric charge having a polarity opposite
to that of the charged visible image, during a passage of the
recording medium through a nip between said body means and
said conductive transfer roller member.
