<p>A method of reproducing multiplex images wherein an electrostatic image is formed on an image retainer (1) by using a common electrostatic image forming device, the electrostatic image formed on the image retainer (1) is developed, the steps of the above are repeated to superpose a plurality of toner images on the image retainer (1), and the toner images is transferred on a recording paper by one step. Each developing step is carried out using a bias voltage satisfying the following inequalities: 0.2 </= VAC/(d.f) and: {(VAC/d)-1500}/f </= 1.0 where VAC is the amplitude (V) of AC component of developing bias (V), f is its frequency (Hz), and d is a gap (mm) between the image retainer (1) and a developer feeding carrier (31).</p> |
