Abstract
PURPOSE:To copy at a high speed by bringing an image sheet into close contact with an original, exposing said sheet, changing the fluidity of a coloring precursor in the microcapsule of the image sheet according to the original image, forming an image and then, transferring to an image receiving sheet. CONSTITUTION:The image sheet G is made by coating a carrier with the coloring precursor and with the microcapsule which connotates a light induction material and the image receiving sheet H is made by coating the carrier with a developer which colors the coloring precursor by reacting on it. The image sheet G is carried to an exposure range 3 from a supply roll 1, adheres closely to the original and exposes 4. At that time, light transmission varies according to the density of the original and the viscosity of the light induction material changes. Secondary, the image receiving sheet H is overlapped with the image sheet G ad pressure is applied to it by a developing roller 7, whereby the microcapsule is crushed. Therefore, the difference appears in flowing amounts of the coloring precursor from a capsule exposed with light and that from an unexposed capsule. Then, the image is formed and transferred to the image receiving sheet H. Hence the image sheet and the original are brought into close contact with each other so that copying can be performed through the use of a simple structure.
