    (54) Electrophotographic process


    (57) An electrophotographic process uses a developer (4) in which the colorant (6) is dispersed in an electrically insulating organic material (5) being solid at room temperature and liquified by heating (8).
    The developer is superior in ease of handling and capable of producing stable images at all times. An electrostatic latent image is wet developed by the developer.
    For recording and preserving the developed image, it is transferred to a transfer substrate. The developed image is transferred by contact of a photoconductor with the transfer substrate, or by peeling a film from a photoconductor.
