<p>PURPOSE:To make transfer efficiency excellent, to prevent frictional toner from being produced and to miniaturize a device by using specified toner and performing transfer and fixing to a preheated recording medium at the same time. CONSTITUTION:The toner 10 is capsule toner consisting of a thermoplastic core material containing thermoplastic resin and colorant, and an outer shell coating the surface of the core material which is made of amorphous polyester. A transfer film 17 moving in contact with a photosensitive body 1 is used, and an electrostatic latent image is formed by sticking the toner 10 on the film 17. The recording medium 6 is previously heated by a heater 4 in order to fix the toner 10, and fed to a pressure roller 5a. The film 17 is brought into contact with the rotating photosensitive body 1 between an electrostatic charging stage and an exposing stage, and separated therefrom after a transfer and fixing stage. Meanwhile, after the surface of the recording medium 6 is heated by preheating, the medium 6 passes the pressure roller 5a, and transfer and fixing are performed to the medium 6 at the same time. Therefore, the transfer and fixing stage is simplified and the device is miniaturized.</p> |
