ABSTRACT:
An electrostatic latent image is formed by the Carlson process, etc. on a base (photosensitive body) to develop the electrostatic latent image by a solidification developer in which coloring agent particles are dispersed into a dispersion medium in a solid state at an ordinary temperature and adapted to reversibly repeat fusion by heating at about 30.degree. C. at a temperature above a melting point and solidification by cooling, thus to form a developer picture. Thereafter, the base and a transferred body are caused to be subjected to pressure-contact and heating process to fuse the dispersion medium at a pressure-contact and heating temperature more than the melting point of the dispersion medium to subsequently cool the dispersion medium down to a temperature less than the melting point to peel the transferred body to transfer the developer picture onto the transferred body. Alternatively, the dispersion medium is softened at a pressure-contact and heating temperature set so that this temperature falls within a range where it is not above the melting point to subsequently peel the transferred body to transfer the developer picture onto the transferred body. On the surface of a recording paper, a resin layer compatible with a dispersion medium of a developer may be formed.
