PURPOSE:To realize a high-reliability, small-sized, and inexpensive printing device which obtains images of high picture quality with high density by using a microcapsule toner for a developer and applying pressure thereto, and transferring a toner image from a photosensitive body to recording paper and fixing the image. CONSTITUTION:A photosensitive body 1 is charged electrostatically by an electrostatic charger 2, image exposure is carried out by an exposing device 3, and the light irradiated part is discharged electrostatically and selectively to form a latent image on the photosensitive body 1. This latent image is developed into a visible image by sticking microcapsule toner 5 which is charged electrostatically by a developing device 4 selectively according to the latent image. At this point of time, the capsule toner 5 sticks on the photosensitive body 1 electrostatically. Then, a form is fed from a paper feeding part at transfer timing and pressed against the photosensitive body 1 by a transfer roller 6. The capsule toner 5 pressed between the paper and photosensitive body has capsules destroyed and liquid ink flows out and is absorbed by the recording paper. The liquid ink is absorbed by the paper immediately, so there is no deficiency in image density due to low transfer efficiency like powder toner transfer and the density of the image is improved. |
