Abstract
An image supporting medium coated with microcapsule toner particles is exposed according to an image pattern, and then a latent image is formed thereon. The image supporting medium on which the latent image is formed and the image recording paper are superposed and pressurized, and the microcapsule toner particles are ruptured and the contents included therein are released. During this process, hardened microcapsule toner particles and wall material of the ruptured microcapsule toner particles from which the contents flowed remain on the image supporting medium by a keying effect, and only the contents, i.e. the toner, are transferred onto the image recording paper. Moreover, the critical surface tension of the wall material of the microcapsule toner particles is smaller than the surface tension of the contents of the microcapsule toner particles. Further, the surface tension of the contents of the microcapsule toner particles is smaller than the critical surface tension of the image recording paper confronting with the image supporting medium. Thus, only the contents of the microcapsules, i.e. the toner, are transferred to the image recording paper. Therefore, a clear and accurate image is formed thereon.
