Abstract
Image forming equipment for applying heat to a charged image carrier to attenuate part of the potential of the image carrier in order to form a latent image on the image carrier. The surface of a dielectric image carrier is charged by a charger and a thermal print head is driven in response to image information in order to form a latent image on the charged surface of the image carrier. A developing roller applies a liquid developer to the latent image and presses it against the portion where the potential has been lowered. The resulting toner image formed on the image carrier is fixed on a paper sheet fed from a paper feeding device or is directly fixed on the image carrier. The image carrier is formed of polyethylene terephthalate or a mixture of polybutylene terephthalate and silicon dioxide.
