形成された複数の静電潜像を、夫々異る色のトナ
ーで現像し同一の転写紙に順次重畳転写すること
により多色複写像を得る電子写真装置において、
１色おきの現像部と転写位置との間に、現像され
たトナー像の極性を変換する手段を設けるととも
に、転写手段の極性を一画像転写毎に変換可能と
し、１つのトナー像を転写する毎に次のトナー像

トナー像の極性と逆極性に変換するように制御す
ることを特徴とする電子写真装置。 An electronic method that obtains a multicolor copy image by developing a plurality of electrostatic latent images formed on an electrophotographic photoreceptor by exposing it to light, each with a different color toner, and sequentially superimposing and transferring them onto the same transfer paper. In photographic equipment,
A means for converting the polarity of the developed toner image is provided between the developing section for every other color and the transfer position, and the polarity of the transfer means can be changed for each transfer of one image, so that one toner image is transferred. An electrophotographic apparatus characterized in that the polarity of a transfer means is controlled so as to convert the polarity of the next toner image to a polarity opposite to that of the toner image every time.
