ABSTRACT:
An image forming apparatus for forming visible images on a recording medium according to source image information, comprises microcapsules, a stirring roller, a photosensitive drum, a microcapsules coating device, a corotron, an exposing device, a heater and a developing device. Each of the microcapsules includes a chromogenic material and a material having a heat-softening property wherein it is softened by heat and a photocuring property wherein it is cured by light. The stirring roller frictionally charges the microcapsules. The photosensitive drum has an electrically chargeable drum surface, the drum surface permits electrostatic latent image to be formed therein according to the source image information. The microcapsules coating device coates the charged microcapsules onto the drum surface of the photosensitive drum according to the electrostatic latent images. The corotron transfer the microcapsules from the drum surface of the photosensitive drum to the recording medium. The exposing device exposes the microcapsules to a radiation having the source image information, so as to selectively cure the microcapsules according to the source image information. The heater heads the microscapsules so as to soften the microcapsules before the microcapsules the pressed by the developing device. The developing device presses the recording medium so as to rupture the softened microcapsules on the recording medium, whereby the visible images are formed on the recording medium.
