ABSTRACT:
In a first embodiment of the present invention, a plurality of electrode portions are contactably and approachably disposed on an electrostatic latent image holding member in order to equalize a toner image of an electrostatic latent image holding member. In a second embodiment, an elastic foaming apparatus is contactably or approachably disposed to the electrostatic latent image holding member in order to equalize the residual toner distribution on the electrostatic latent image holding member. In a third embodiment, an equalization member consisting of an electric conductor or a resistor is contactably and approachably disposed on the electrostatic latent image holding member in order to equalize the distribution of toner of the transfer residual toner image. An AC electric field may be generated between the equalization member and the electrostatic latent image holding member.
