Abstract
PURPOSE: To eliminate surely the tetrafluoroethylene particles out of the system, by transferring the particles along with the toner to the transfer paper and with the initial negative electrification kept as it is.
CONSTITUTION: The tetrafluoroethylene coating of the carrier is worn away gradually by the stirring and carrying within a developing device, and the filings are turned into the fine particles 22 electrified with the negative charge to stick to the toner 19 of positive electrification. Then the particles 22 are adsorbed to the surface of the ptotoreceptor along with the toner 19 during the developer. After the development, the toner 19 on the photoreceptor and the tetrafluoroethylene fine particles 22 are electrified negative again by the corona discharger 23 and then transferred. As the transfer roller 24 is earthed, an electric filed slope is caused between the roller 24 and the potential of the latent image on the photoreceptor. Then an electric field is generated from the photoreceptor and going toward the roller 24. As a result, both the toner 19 having the same polarity as the latent image and the particles 22 detach from the photoreceptor and then stick to the transfer paper 25 to perform the transfer. Accordingly, the particles 22 are exhausted out of the system.
