ELECTROSTATIC COLOUR PRINTING APPARATUS

摘要

Electrostatographic colour printing apparatus which comprises exposure units (29, 29') for forming successive electrostatic colour part images on both surfaces of a recording member in the form of an endless belt (26), developing stations (35, 36, 37, 38, 35', 36', 37', 38') for sequentially developing such electrostatic latent images to form toner images on such belt, and electrostatic transfer stations (40, 41, 42, 43, 40', 41', 42', 43') for sequentially transferring the toner images from such belt in superposition onto a receptor sheet fed through the transfer stations while in contact with a belt section therein to produce a multicolour duplex image.
