摘要：Writing electrodes of a writing device are kept in contact with a latent imagecarrier with a small pressing force by a weak restoring force of a substrate. An

electrostatic latent image is written on the latent image carrier by applying or removingcharge relative to the latent image carrier which is already uniformly charged by a chargecontrol device. The application or removal of charge is conducted via charge-transferbetween the latent image carrier and the writing electrodes which are in contact witheach other. The electrostatic latent image is developed by a developing device to form adeveloping powder image and this developing powder image is transferred to a receivingmedium such as a paper by a transferring device. Since the writing electrodes areemployed as the writing device, the apparatus can be manufactured smaller and simplyand can steadily write an image.
