Abstract

PURPOSE:To make possible transfer of two color images to plain paper by developing positive and negative electrostatic latent images with color toners of different polarities then unifying the toner polarities with a corona charger. CONSTITUTION:The positive and negative electrostatic latent images having been formed on a dielectric drum 3 according to the original image colors are developed by color toners of differect polarities according to the image colors being supplied from a developing device 5. These toner images become of the same polarity by the charging with destaticzing corona chargers 11, 12 with AC grids of opposite polarities. Hence, the two color toner images may be transferred at a high speed to the plain paper.
