摘要： 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.

The carrier includes a hole through which a stick member penetrates in a direction of axis of rotation of the carrier. The stick member penetrates through the hole and is mounted on the stick mount. The stick mount is disposed opposite the carrier. The outer gear and the sun gear are held such that one of the outer gear and the sun gear does not rotate.
