ABSTRACT:
To form an optical image, an imagewise pattern of conductivity is formed in a semiconductor material. Exposing the material to an intense radio-frequency field causes generation of heat in the conductive areas. The semiconductor is made of a heat-sensitive material or includes a heat-sensitive material. The heat-sensitive material responds to heat by physical changes which can be optically detected. Preferably the semiconductor is a photoconductor with surface charge capability retention which allows formation of a conductivity pattern by normal xerographic processes.
